stainless steel wire rope breaking strength factory

Nylon coated stainless & galvanised wire ropes & miniature wire ropes can be used for all non-aerospace applications & come in a variety of sizes & colours supplied with test certification. Nylon coating is quite easy to strip & can be coloured with almost any base colour (subject to quantity required). Nylon coating is suitable for working over sheaves - cable & coating life is very dependent upon the material, diameter & profile of the sheaves over which it runs.

When it comes to choosing the right wire rope, you need to ensure you choose the materials best suited to meet your application’s needs, while also being sensitive to budget. This requires working with the right stainless steel wire supplier that meets ISO 9001 requirements. Stainless steel wire rope manufacturers like Carl Stahl Sava Industries know that it is cost-effective, strong, durable, corrosion-resistant, and heat resistant. This makes stainless steel among the more popular cable rope materials that Sava works with precisely due to its wide range of applications and affordability.

Stainless steel wire rope suppliers often recommend it over other cable construction materials because of its cost-effectiveness. But what’s interesting about stainless steel stranded wire is that its affordability, as compared with more expensive alternatives like tungsten for example is rooted in its low maintenance, longevity, availability and ease of use and installation. Therefore the material’s mechanical malleability, including its lifespan, combined with how readily available it is, makes stainless steel ideal in many use cases.

As a stainless steel wire rope supplier & manufacturerSava typically works with industry-standard stainless steel, such as 303, 304 and 316 stainless steel. However, we can work with any stainless steel a customer needs,and through our stainless steel wire fabrication process we provide a product other wire rope manufacturers, suppliers, and stainless steel wire rope factories cannot. We are a wire rope supplier of over-the-counter stainless steel cable and manufacture an entire family of cable fittings to create your custom cable assembly.

Another reason stainless steel is an industry-standard is because of stainless steel wire rope’sstrength and durability. It is an exceptionally strong wire.

For example, Grade 301 and 304 stainless steel possesses a tensile strength of up to 1300 MPa in strip and wire forms. Galvanized steel, with a tensile strength of up to 550 MPa, comparatively, makes stainless steel remarkably strong.

Consequently, stainless steel has a long lifespan, although not as long as tungsten due to the latter’s tolerance of more intense temperatures. Even so, stainless steel is effective in a wide range of applications over many cycles, making it ideal across many applications.

As mentioned, tungsten is preferable in extremely hot environments that require a long life span, because it heats up quickly but dissipates the heat equally as fast. However, stainless steel can perform at these same levels of extreme heat and at a lower cost, but over less cycles. But that it doesn’t last as long as tungsten under extreme conditions doesn’t rule it out. For instance, if you have an operation that needs a high lifecycle, but it’s not being used as frequently, stainless steel mechanical cable might be perfect. If cycles are less frequent, then it’s possible stainless steel will last as long as the application requires and again, under the same hostile temperatures that gives tungsten all the glory.

So, while tungsten certainly has its benefits, stainless steel mechanical cable is a strong alternative that will provide similar, if not the same, results for most applications.

Another feature that makes stainless steel cable advantageous is that it’s easy to work with, compared to other materials. It is very easily formed, especially in the small-diameter wires inside the cable as well. What’s more, stainless steel mechanical cable is also easy to lay into the appropriate shape when stranded.

When the stainless steel cable is manufactured with a nitinol core, the results possess seemingly magical easy-to-use properties. Known as a memory alloy, nitinol “remembers,” so-to-speak, the shape it was in, allowing the stainless steel cable housing the nitinol core wire to traverse winding and twisting pathways like arteries and other narrow vessels. In such surgical applications, this nitinol core wire is the center of the stranded cable otherwise comprised of stainless steel. So when paired with nitinol, stainless steel cable becomes a flexible, memory-based solution for a wide array of medical devices that use medical cable assemblies, and medical grade stainless steel wire. But as nitinol is not used to comprise the entire stranded cable used in these elegant medical devices, stainless steel remains the best material to work with when bending is critical, but cost is equally important.

If your application requires sensitivity to corrosion, such as weather or water, salt or otherwise, stainless steel cable is an excellent choice. The material’s tolerance of harsh environmental conditions ensures the cable can take a beating over a long period of time by moisture. Comparatively speaking, galvanized steel, another steel cable Sava manufacturers, is vulnerable to applications where corrosive variables are present, like marine or submerged saltwater uses.

This also means it is not as strong as either 1x19 or 7x7. 7x19 wire rope is suitable for most running load applications & numerous applications such as security cables & winch cables.

Alternate Lay:inner core and outer core wires are twisted in opposite direction. Usually consists of alternating regular lay and lang lay strands—used mainly for special applications.

Breaking Strength:the average force at which the product, in the condition it would leave the factory, has been found to break when constantly increasing force is applied in direct line to the product at a steady rate of speed on a standard pull testing machine. Published breaking strength were acquired during controlled laboratory conditions. Always refer to the

Extra improved plow steel (EIPS): also known as XISP, this steel material is used in producing wire ropes for special installations, where maximum rope strength is required. It has a minimum breaking strength 15 percent higher than

Fiber Core:standard wire rope that has synthetic fiber at the center of the wire. Fiber cores are very pliable and yielding, but have the downside of getting crushed easily.

Improved Plow Steel (IPS):steel material that has between 0.5 and 0.95 percent carbon. It is considered one of the best grades of wire ropes available. Strong, more durable and wear-resistant than normal plow steel.

Independent Wire Rope Core (IWRC):the most durable type of core for standard wire rope in most environments compared to synthetic core and wire strand core.

Lang Lay (LL):wires are all twisted in the same direction. Lang lay ropes aremore pliable than regular lay ropes and have greater wearing surface per wire than regular lay ropes. Recommended for many excavating, construction, and mining applications, including drag lines, hoist lines, dredge lines and other similar lines.

Minimum Breaking Strength (MBS):the minimum amount of force required to break this object. Often referred to as tensile strength or breaking strength. Not to be confused with Yield Strength.

Right Regular Lay (RRL):the direction of wire twist; right hand. Wires in the wire rope strands are laid opposite in direction to the lay of the strands. This designation has the broadest variety of utilizations and meets the requirements of most equipment. Compared to RRL, most other lay designations are deemed as exceptions and usually require special ordering.

Safety Working Load (SWL):the load that can be applied to a line without causing any kind of damage to the wire rope. Note that the safe working load is considerably less than the breaking strength.

Wire rope and cable are each considered a “machine”. The configuration and method of manufacture combined with the proper selection of material when designed for a specific purpose enables a wire rope or cable to transmit forces, motion and energy in some predetermined manner and to some desired end.

Two or more wires concentrically laid around a center wire is called a strand. It may consist of one or more layers. Typically, the number of wires in a strand is 7, 19 or 37. A group of strands laid around a core would be called a cable or wire rope. In terms of product designation, 7 strands with 19 wires in each strand would be a 7×19 cable: 7 strands with 7 wires in each strand would be a 7×7 cable.

Materials Different applications for wire rope present varying demands for strength, abrasion and corrosion resistance. In order to meet these requirements, wire rope is produced in a number of different materials.

Stainless Steel This is used where corrosion is a prime factor and the cost increase warrants its use. The 18% chromium, 8% nickel alloy known as type 302 is the most common grade accepted due to both corrosion resistance and high strength. Other types frequently used in wire rope are 304, 305, 316 and 321, each having its specific advantage over the other. Type 305 is used where non-magnetic properties are required, however, there is a slight loss of strength.

Galvanized Carbon Steel This is used where strength is a prime factor and corrosion resistance is not great enough to require the use of stainless steel. The lower cost is usually a consideration in the selection of galvanized carbon steel. Wires used in these wire ropes are individually coated with a layer of zinc which offers a good measure of protection from corrosive elements.

Cable Construction The greater the number of wires in a strand or cable of a given diameter, the more flexibility it has. A 1×7 or a 1×19 strand, having 7 and 19 wires respectively, is used principally as a fixed member, as a straight linkage, or where flexing is minimal.

Selecting Wire Rope When selecting a wire rope to give the best service, there are four requirements which should be given consideration. A proper choice is made by correctly estimating the relative importance of these requirements and selecting a rope which has the qualities best suited to withstand the effects of continued use. The rope should possess:Strength sufficient to take care of the maximum load that may be applied, with a proper safety factor.

Strength Wire rope in service is subjected to several kinds of stresses. The stresses most frequently encountered are direct tension, stress due to acceleration, stress due to sudden or shock loads, stress due to bending, and stress resulting from several forces acting at one time. For the most part, these stresses can be converted into terms of simple tension, and a rope of approximately the correct strength can be chosen. As the strength of a wire rope is determined by its, size, grade and construction, these three factors should be considered.

Safety Factors The safety factor is the ratio of the strength of the rope to the working load. A wire rope with a strength of 10,000 pounds and a total working load of 2,000 pounds would be operating with a safety factor of five.

It is not possible to set safety factors for the various types of wire rope using equipment, as this factor can vary with conditions on individual units of equipment.

The proper safety factor depends not only on the loads applied, but also on the speed of operation, shock load applied, the type of fittings used for securing the rope ends, the acceleration and deceleration, the length of rope, the number, size and location of sheaves and drums, the factors causing abrasion and corrosion and the facilities for inspection.

Fatigue Fatigue failure of the wires in a wire rope is the result of the propagation of small cracks under repeated applications of bending loads. It occurs when ropes operate over comparatively small sheaves or drums. The repeated bending of the individual wires, as the rope bends when passing over the sheaves or drums, and the straightening of the individual wires, as the rope leaves the sheaves or drums, causing fatigue. The effect of fatigue on wires is illustrated by bending a wire repeatedly back and forth until it breaks.

The best means of preventing early fatigue of wire ropes is to use sheaves and drums of adequate size. To increase the resistance to fatigue, a rope of more flexible construction should be used, as increased flexibility is secured through the use of smaller wires.

Abrasive Wear The ability of a wire rope to withstand abrasion is determined by the size, the carbon and manganese content, the heat treatment of the outer wires and the construction of the rope. The larger outer wires of the less flexible constructions are better able to withstand abrasion than the finer outer wires of the more flexible ropes. The higher carbon and manganese content and the heat treatment used in producing wire for the stronger ropes, make the higher grade ropes better able to withstand abrasive wear than the lower grade ropes.

Effects of Bending All wire ropes, except stationary ropes used as guys or supports, are subjected to bending around sheaves or drums. The service obtained from wire ropes is, to a large extent, dependent upon the proper choice and location of the sheaves and drums about which it operates.

A wire rope may be considered a machine in which the individual elements (wires and strands) slide upon each other when the rope is bent. Therefore, as a prerequisite to the satisfactory operation of wire rope over sheaves and drums, the rope must be properly lubricated.

Loss of strength due to bending is caused by the inability of the individual strands and wires to adjust themselves to their changed position when the rope is bent. Tests made by the National Institute of Standards and Technology show that the rope strength decreases in a marked degree as the sheave diameter grows smaller with respect to the diameter of the rope. The loss of strength due to bending wire ropes over the sheaves found in common use will not exceed 6% and will usually be about 4%.

The bending of a wire rope is accompanied by readjustment in the positions of the strands and wires and results in actual bending of the wires. Repetitive flexing of the wires develops bending loads which, even though well within the elastic limit of the wires, set up points of stress concentration.

The fatigue effect of bending appears in the form of small cracks in the wires at these over-stressed foci. These cracks propagate under repeated stress cycles, until the remaining sound metal is inadequate to withstand the bending load. This results in broken wires showing no apparent contraction of cross section.

Experience has established the fact that from the service view-point, a very definite relationship exists between the size of the individual outer wires of a wire rope and the size of the sheave or drum about which it operates. Sheaves and drums smaller than 200 times the diameter of the outer wires will cause permanent set in a heavily loaded rope. Good practice requires the use of sheaves and drums with diameters 800 times the diameter of the outer wires in the rope for heavily loaded fast-moving ropes.

It is impossible to give a definite minimum size of sheave or drum about which a wire rope will operate with satisfactory results, because of the other factors affecting the useful life of the rope. If the loads are light or the speed slow, smaller sheaves and drums can be used without causing early fatigue of the wires than if the loads are heavy or the speed is fast. Reverse bends, where a rope is bent in one direction and then in the opposite direction, cause excessive fatigue and should be avoided whenever possible. When a reverse bend is necessary larger sheaves are required than would be the case if the rope were bent in one direction only.

Stretch of Wire Rope The stretch of a wire rope under load is the result of two components: the structural stretch and the elastic stretch. Structural stretch of wire rope is caused by the lengthening of the rope lay, compression of the core and adjustment of the wires and strands to the load placed upon the wire rope. The elastic stretch is caused by elongation of the wires.

The structural stretch varies with the size of core, the lengths of lays and the construction of the rope. This stretch also varies with the loads imposed and the amount of bending to which the rope is subjected. For estimating this stretch the value of one-half percent, or .005 times the length of the rope under load, gives an approximate figure. If loads are light, one-quarter percent or .0025 times the rope length may be used. With heavy loads, this stretch may approach one percent, or .01 times the rope length.

The elastic stretch of a wire rope is directly proportional to the load and the length of rope under load, and inversely proportional to the metallic area and modulus of elasticity. This applies only to loads that do not exceed the elastic limit of a wire rope. The elastic limit of stainless steel wire rope is approximately 60% of its breaking strength and for galvanized ropes it is approximately 50%.

Preformed Wire Ropes Preformed ropes differ from the standard, or non-preformed ropes, in that the individual wires in the strands and the strands in the rope are preformed, or pre-shaped to their proper shape before they are assembled in the finished rope.

This, in turn, results in preformed wire ropes having the following characteristics:They can be cut without the seizings necessary to retain the rope structure of non-preformed ropes.

They are substantially free from liveliness and twisting tendencies. This makes installation and handling easier, and lessens the likelihood of damage to the rope from kinking or fouling. Preforming permits the more general use of Lang lay and wire core constructions.

Removal of internal stresses increase resistance to fatigue from bending. This results in increased service where ability to withstand bending is the important requirement. It also permits the use of ropes with larger outer wires, when increased wear resistance is desired.

Outer wires will wear thinner before breaking, and broken wire ends will not protrude from the rope to injure worker’s hands, to nick and distort adjacent wires, or to wear sheaves and drums. Because of the fact that broken wire ends do not porcupine, they are not as noticeable as they are in non-preformed ropes. This necessitates the use of greater care when inspecting worn preformed ropes, to determine their true condition.

Bright steel wire ropes mean no surface treatment is applied to the rope. Therefore, they have the lower price among these three wire ropes. Generally, they are fully lubricated to protect the rope from rust and corrosion.

Galvanized steel wire ropes feature compressed zinc coating for providing excellent corrosion resistance. With higher break strength yet lower price than stainless steel, galvanized steel wire ropes are widely used in general engineering applications such as winches and security ropes.

Stainless steel wire ropes, made of quality 304, 305, 316 steels, are the most corrosive type for marine environments and other places subjected to salt water spray. Meanwhile, bright and shiny appearance can be maintained for years rather than dull as galvanized steel wire ropes.

Steel wire ropes are composed of multiple strands of individual wires that surrounding a wire or fiber center to form a combination with excellent fatigue and abrasion resistance. These wires and strands are wound in different directions to from different lay types as follows:

Beside above lay types, alternative lay ropes which combine regular lay and lang lay together and ideal for boom hoist and winch lines, can also be supplied as your request.

Two main methods about seizing steel wire ropes in conjunction with soft or annealing wire or strands to protect cut ends of the ropes form loosening.
