What is Stainless Wire Rope？

Stainless steel wire rope, as the name implies, is a wire rope made of stainless steel. Stainless steel is an alloy steel that mainly contains elements such as chromium (Cr) and nickel (Ni), which give it excellent corrosion resistance and oxidation resistance. Stainless steel wire rope is made by twisting multiple strands of stainless steel wire in a specific way to form a rope with high strength, high flexibility, and good wear resistance. It can maintain stable performance in various harsh environments, so it is widely used in many industries.

 

Common structures

The structure of stainless steel wire rope is usually made of multiple strands of steel wires. Common structures include:

1) 1×7 structure: composed of 1 center wire and 6 outer wires, suitable for light load scenarios.

2) 1×19 structure: composed of 1 center wire and 18 outer wires, with higher strength and rigidity.

3) 7×7 structure: composed of 7 strands of steel wire rope, each strand is twisted with 7 steel wires, suitable for medium loads.

4) 7×19 structure: composed of 7 strands of steel wire rope, each strand is twisted with 19 steel wires, with higher flexibility and fatigue resistance.

Advantages of stainless steel wire rope

1. Strong corrosion resistance: Stainless steel material gives the wire rope excellent corrosion resistance, and can maintain stable performance for a long time in humid and corrosive environments.

2. High strength: Through the precise twisting process, the ss wire rope can withstand large tension and is suitable for heavy loads and occasions requiring a high safety factor.

3. Good flexibility and wear resistance: stainless steel wire cable has good flexibility and wear resistance, and can adapt to various complex bending and twisting movements while maintaining a long service life.

4. High dimensional accuracy: The dimensional accuracy of stainless steel cable rope can reach ±0.01mm, ensuring its reliable application in various precision equipment.

5. Safety: High strength and high reliability make it a safe choice in critical applications, such as lifting equipment and bridge cables.

6. Versatility: The structure and specifications of a stainless steel cable are diverse, which can meet the needs of different scenarios.

7. Aesthetics: The surface of stainless steel is smooth and has a metallic luster, which is suitable for occasions with high requirements for appearance.

Uses

Stainless steel wire rope is important in many fields due to its excellent performance. Here are some of the main application scenarios:

1. Coal, petroleum, metallurgy: used for hoisting, traction, fixing, and other occasions, subject to huge tension and wear.

2. Chemical, fertilizer, chemical fiber: connectors, lifting rings, etc., to ensure the safe operation of the equipment.

3. Ship, bridge, electricity: cables, slings, etc., subject to huge tension and vibration.

4. Tourism, water conservancy, and light industry: used for amusement facilities, water conservancy facilities, light industrial equipment, and other occasions.

5. Safety protection fields: such as anti-fall nets, stainless steel rope nets, etc., provide strong protection for people’s lives and property safety.

6. Architecture: support and fixation of glass curtain walls of high-rise buildings.

7. Aerospace: used for aircraft control cables, requiring high strength and fatigue resistance. Used for the support and adjustment of satellite antennas.

8. Daily life: stainless steel chandeliers, decorative structures such as stair handrails and guardrails, climbing ropes, bungee ropes,s and other sports equipment.

What are the types of Stainless Wire Rope?

Stainless steel wire rope can be divided into many types according to structure and material. The following are 3 main classification methods:

 

Ⅰ. Classification by material

1. 201 stainless steel wire rope: has good corrosion resistance, heat resistance, and low-temperature strength, but its corrosion resistance is slightly weaker than 304 and 316 materials.

2. 304 stainless steel wire rope: the most common austenitic stainless steel, with good corrosion resistance, heat resistance, and low temperature strength, widely used in food and medical equipment.

3. 316 stainless steel wire rope: Molybdenum (Mo) is added to 304 to improve the resistance to pitting and crevice corrosion. It is the noblest among stainless steels and is suitable for marine environments and chemical industries.

Here is an article that comprehensively describes the differences between 316 and 304 stainless steel for your reference.

 

Ⅱ. Classification by structure

1. Single-strand structure: such as 1×3, 1×7, 1×19, etc., suitable for light loads and occasions requiring higher flexibility.

2. Multi-strand structure: such as 7×7 (6×7+WSC), 7×19 (6×19+WSC), 6×37, etc., suitable for heavy loads and occasions requiring higher wear resistance.

 

Ⅲ. Classification by contact form

1. Point contact: The adjacent layers of steel wires in a strand are in point contact, the structure is relatively loose, and it is suitable for light loads.

2. Line contact: The adjacent layers of steel wires in a strand are in line contact, the structure is tighter, and it is suitable for medium and heavy loads.

3. Surface contact: The adjacent layers of steel wires in a strand are in surface contact, which has higher strength and wear resistance, and is suitable for heavy loads.

Manufacturing process of stainless steel wire rope

The manufacturing of stainless steel cables in each steel plant follows the following steps:

Select high-quality stainless steel that meets the standards → Drawing through a wire drawing machine → Twisting into strands → Twisting into ropes (note the direction is left-hand or right-hand twist, control the twist length) → Heat treatment → Surface polishing or coating treatment → Mechanical properties test and appearance inspection → Standard packaging

Specific steps

1. Raw Material Preparation: Select standard stainless steel wire rod, such as 304 or 316 stainless steel wire rod, and pickle and anneal it.

2. Wire Drawing: The wire rod is drawn through drawing dies of varying apertures, gradually reaching the desired diameter while lubricating and cooling the wire rod to prevent heat damage.

3. Stranding: Multiple stainless steel wires are twisted into strands (common strand structures include 1×7 and 1×19) using a stranding machine according to a predetermined lay direction (left-hand or right-hand lay) and lay pitch.

4. Roping: Multiple strands (usually 6 strands + 1 fiber or steel core) are wound onto a central core (fiber or steel core) using a rope closing machine according to the specified lay direction and lay pitch, forming a complete stainless steel wire rope.

5. Heat Treatment: The rope undergoes a stabilization heat treatment, such as low-temperature tempering, to eliminate internal stresses and enhance overall strength and toughness. 6. Surface Treatment: Common treatments include electropolishing to improve surface finish and corrosion resistance, passivation to form an oxide film for enhanced rust resistance, and PVC coating to further enhance protection.
7. Inspection & Cutting: Qualified products are screened through visual inspection for broken wires and deformation, dimensional measurements such as diameter and lay length, and mechanical property tests such as tensile strength and breaking strength. Finally, products are cut to specified lengths as required.

Maintenance and care of stainless steel wire rope

Although stainless steel rope has excellent corrosion resistance, it still needs regular maintenance in some extreme environments:

1. Regular inspection: Check the surface of the wire rope for wear, broken wires, or corrosion.

2. Cleaning: Clean and wipe the surface with clean water or neutral detergent, avoid using acidic or alkaline detergents.

3. Lubrication: Lubricate the wire rope to reduce friction and wear.

4. Replacement: When the wire rope is broken, it should be replaced in time to ensure safety.

Stainless steel wire rope price

The price of stainless steel wire rope varies by region, supplier, and market conditions.

3. Special structure or treatment

The price of wire rope with 7×19 structure is about 20%-50% higher than that of 1×7 structure.

The price of PVC coated wire rope is about 30%-100% higher than that of ordinary wire rope.
