430 Stainless Steel Wire

Stainless Steel Products stocks 430 Alloy in various diameters. This is considered a ferritic stainless steel. Its strengths are in its ductility, formability, good corrosion and oxidation resistance, thermal conductivity and finish quality. We can harden this alloy through cold working.


Stainless Steel 430 alloy is one of the most popular non-hardening stainless-steel alloys, and offers a long list of benefits when made into wire:

  • Cost-effective
  • Low carbon
  • Non-hardening steel
  • Weldable
  • Can be cold worked

Having the right blend

Stainless Steel 430 alloy is a blend of carbon, chromium, iron, manganese, nickel, phosphorus, silicon and sulfur materials. Stainless Steel 430 alloy is composed of:

Carbon0.12, max.
Silicone0.75, max.
Manganese1.00, max.
Phosphorus0.040, max.
Sulfur0.030, max.
Nickel0.60, max.
