Stainless steel 302 wire rope with 1x7 standard construction is commonly used for rigging, hoisting, push-pull, and guying applications. Stainless steel 302 has corrosion-resistance and strength, compared to galvanized carbon steel grades. This commonly used material has the same resistance as 304, but additional carbon provides higher strength. 1x7 strand core is a single-strand construction that has one strand of wire rope with seven wires in each strand, formed helically around a strand core. 1x7 strand core is a common type that offers some abrasion resistance for ease of operation. This wire rope can be used in both large and small diameters for a wide range of applications. Wire rope, also called wire cable, is an assembly of wire strands formed helically around a central core. It is used for pulling, lifting, rigging, hoisting, and motion-control applications most commonly found in the manufacturing, marine, oil, mining, fiber-optics, aircraft, automotive accessory, and construction industries. A combination of characteristics including material, finish, construction, diameter, length, and breaking strength combines to give each rope its performance ability. Wire rope materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. For strength purposes, most wire rope is made of bright (uncoated or bare) wire. However, it is also produced in a variety of finishes, such as polypropylene (PE), vinyl (PVC), or nylon. These coatings can increase overall durability and strength, and allow for specific use. The breaking strength for wire rope is the strength at which new wire rope will fail under a stationary load. Breaking strength is not considered safe working load (SWL) limit.
