China [CN] Stainless steel wire rope is a type of cable made from strands of stainless steel wires twisted or braided together to form a highly durable and flexible rope. This rope is crafted from stainless steel, renowned for its resistance to corrosion and rust, making it ideal for use in harsh or marine environments. The most common materials used are grades 304 and 316, with 316 offering higher corrosion resistance and being preferred for marine applications.
Materials
- 304 Stainless Steel: Good overall strength and corrosion resistance. It’s suitable for a wide range of environments but less ideal for highly corrosive settings.
- 316 Stainless Steel: Offers excellent corrosion resistance, making it ideal for marine and harsh environments due to its superior resistance to salt and chemicals.
- 316L Stainless Steel: Similar to 316 but with lower carbon content, which helps minimize the risk of corrosion from welding. This grade is excellent for welded structures, especially in marine environments.
Wire Diameter
The thickness of individual cables, usually ranging from 1mm to 4mm (0.039 to 0.157 inches), which determines the strength and flexibility of the mesh.
Common Configurations
- 7×7 (also known as 6×7+FC): This configuration consists of six strands of seven wires each, around a fiber core. It offers a good balance between flexibility and resistance to abrasion and is suitable for use in pulleys and rigging.
- 7×19 (also known as 6×19+FC): Made up of six strands of 19 wires each, also around a fiber core, this type is highly flexible and ideal for dynamic load applications like cranes and hoists.
- 1×19: Consists of a single strand with nineteen wires. Very stiff and has a smooth surface, making it ideal for straight line applications where little bending is required, such as rigging, mast stays, and architectural uses.
- 6×36: Made up of six strands, each containing thirty-six wires. Offers a good balance between abrasion resistance and flexibility, making it suitable for bending over pulleys and winches in hoisting and towing applications.
- 8×19: Consists of eight strands, each with nineteen wires. Provides increased flexibility over the 6×19 construction, used for hoisting applications where the wire rope needs to bend frequently.
- 19×7: Nineteen strands, each with seven wires. A non-rotating rope type that is particularly useful in crane applications, where the load must not spin under the wire rope.
- 6×25: Features six strands, each composed of twenty-five wires. It strikes a balance between flexibility and wear resistance, suitable for varied mechanical applications where both properties are valued.
- 18×7 and 17×7: Composed of either eighteen or seventeen strands, each with seven wires. These are rotation-resistant ropes, slightly less stiff than 19×7, ideal for hoisting applications where rotation of the load can be a problem.
