Stainless Steel Wire Characteristics
- Stainless steel wire is used when high strength and corrosion resistance is important in an application.
Stainless Steel Wires Vary By:
1. Type 2. Diameter 3. Hardness 4. Tensile 5. Surface Condition
Wire Types
- Each TYPE has a different allowable range of CHEMICAL COMPOSITION to meet various performance requirements.
