7×19 Stainless Steel Wire Rope Overview
7×19 stainless steel wire rope provides excellent flexibility, corrosion resistance and reliable strength for applications requiring repeated bending, pulley operation and flexible cable routing. It is available in AISI 304, 316 and 316L stainless steel, with custom diameters, lengths, reels and cable assemblies.
Compared with 7×7 and 1×19 constructions, 7×19 wire rope contains more individual wires, providing greater flexibility and improved bending performance. This makes it suitable for applications involving pulleys, sheaves, control systems and other moving cable assemblies.
AISI 304 is commonly used for general industrial and architectural applications, while AISI 316 and 316L are generally preferred for marine, coastal and more corrosive environments.

Key Features
High Flexibility
The 7×19 construction contains a large number of individual wires, providing higher flexibility than 7×7 and 1×19 stainless steel wire rope.
This makes it suitable for cable systems requiring bending, movement or routing around equipment.
Stainless Steel Material Options
7×19 stainless steel wire rope can be supplied in:
- AISI 304
- AISI 316
- AISI 316L
AISI 304 is commonly selected for general industrial and architectural applications.
AISI 316 and 316L are generally preferred for marine, coastal, humid and more corrosive environments.
Wide Diameter Range
Reference sizes are available from 1.0 mm to 26.0 mm, depending on the required specification.
Custom sizes can be discussed according to project requirements and production capability.
Custom Supply Formats
7×19 stainless steel wire rope can be supplied as:
- Coils
- Reels
- Cut lengths
- Custom cable assemblies
- Wire rope with terminals or fittings
- OEM packaging and labeling
Applications
Our 7×19 stainless steel wire rope is commonly used in:
- Pulley and sheave systems
- Fitness equipment
- Control cables
- Marine and yacht applications
- Winches and lifting-related cable systems
- Safety cables
- Industrial machinery
- Architectural cable systems
- Suspension systems
- Flexible wire rope assemblies
- General industrial and engineering applications
For applications involving continuous bending over pulleys or sheaves, the pulley diameter, operating load, bending frequency and D/d ratio should be confirmed before final rope selection.
How to Choose 7×19 Stainless Steel Wire Rope
Selecting the correct stainless steel wire rope depends on the required flexibility, operating environment, diameter, load and installation method.
For general outdoor and industrial applications, AISI 304 may provide a practical balance between corrosion resistance and cost.
For marine, coastal, high-humidity or more corrosive environments, AISI 316 or 316L is generally preferred.
The construction should also match the movement requirement:
| Construction | Flexibility | Typical Selection |
|---|---|---|
| 1×19 | Low | Rigid tension and architectural applications |
| 7×7 | Medium | General cable and low-cycle applications |
| 7×19 | High | Repeated bending and flexible cable applications |
For equipment using pulleys, drums or sheaves, please provide the pulley diameter, cable diameter, operating load and bending frequency for specification review.
304 vs 316 Stainless Steel Wire Rope
Both AISI 304 and AISI 316 stainless steel wire rope provide corrosion resistance, durability and a clean stainless steel finish.
| Item | AISI 304 | AISI 316 / 316L |
|---|---|---|
| General corrosion resistance | Good | Improved |
| Indoor applications | Suitable | Suitable |
| General outdoor use | Suitable | Highly suitable |
| Marine environments | Limited depending on exposure | Generally preferred |
| Coastal applications | Depends on environment | Generally preferred |
| Industrial applications | Commonly used | Commonly used |
| Relative cost | More economical | Higher |
AISI 316 contains improved corrosion-resistant alloying compared with AISI 304 and is commonly selected for saltwater, coastal and aggressive environments.

FAQ
What is 7×19 stainless steel wire rope?
7×19 stainless steel wire rope is a flexible multi-strand wire rope construction containing a large number of individual wires. It is commonly selected where greater bending flexibility is required.
What is the difference between 7×7 and 7×19 stainless steel wire rope?
7×7 provides moderate flexibility and good structural stability.
7×19 contains more individual wires and is therefore generally more flexible, making it more suitable for applications involving repeated bending, pulleys or moving cable systems.
Is 7×19 more flexible than 7×7?
Yes. In general, 7×19 stainless steel wire rope provides greater flexibility than 7×7 construction.
Can I choose AISI 304 or AISI 316?
Yes. AISI 304, 316 and 316L can be selected according to the operating environment and project requirements.
AISI 316 or 316L is generally preferred for marine, coastal and more corrosive environments.
Can 7×19 stainless steel wire rope be used with pulleys?
7×19 is commonly selected for applications requiring greater flexibility and bending. However, the pulley diameter, D/d ratio, load and bending frequency should be checked before final selection.
Can you supply custom lengths and fittings?
Yes. Wire rope can be supplied in cut lengths, coils, reels or customized assemblies with compatible ferrules, thimbles, terminals and other fittings.
What information should I provide for a quotation?
Please provide the stainless steel grade, diameter, required length, quantity, application, destination country and any required fittings or packaging.
