Compare
How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| Carbon steel wire rope | Stainless steel offers superior corrosion resistance but has lower tensile strength and higher cost |
| 6x19S+FC | The IWR core provides better crush resistance and load distribution than fibre core, especially under dynamic or high-pressure conditions |
| 6x36S | The 6x19S+IWR has higher tensile strength and better abrasion resistance than 6x36S, though it is less flexible |
| Galvanized steel rope | Stainless steel resists corrosion in aggressive environments where galvanizing fails, but it is heavier and more expensive |
Use Guide
How To Use And Inspect Stainless Steel Wire Rope 6x19S+IWR
- Verify the minimum breaking load and working load limit match the application load and safety factor
- Inspect the rope for kinks, flattening, or broken wires before each use
- Use the correct sheave diameter to prevent premature fatigue and surface damage
- Avoid sharp bends or side loading that can cause internal wire damage
- Do not use if the core is visible or the rope shows signs of corrosion or deformation
- Replace the rope if the diameter has reduced by more than 7% or if more than 10% of wires are broken in a single lay
