Useful Technical Charts

Below are some useful technical charts you may want to use when designing your products. Please call us for application engineering assistance or technical product recommendations. 

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.

Wire Hardness

  • The end-use of the wire will dictate the preferred HARDNESS. Hardness can vary from vary from very soft (dead soft annealed) to very hard (spring temper).
