430 Stainless Steel Wire Mesh – Alloy Overview

Type 430 stainless steel wire mesh is the most commonly used ferritic stainless steel alloy, and has a chromium content of 16-18%. Being a ferritic stainless steel, T-430 cannot be strengthened or hardened by heat treatment, but is more resistant to chemical attack and high temperatures when compared to T-410 stainless steel. As such, T-430 stainless steel displays good resistance to nitric acid, some organic acids, and a broad mix of other corrosive environments. Some characteristics of 410L stainless steel wire cloth which dictate its use are:

  • Ferritic stainless steel.
  • Magnetic in all conditions.
  • Max operating temperature of ~1500°F.
  • Resists oxidation at 1600°F temperatures, though strength loss occurs above 1300°F.
  • Can be cut, formed, and welded.

Industries & Applications

T-430 stainless steel wire cloth is principally used with food products, chemicals, and appliances given its previously mentioned resistance to nitric and organic acids. T-430 has similar resistance to crevice corrosion and pitting as T-304, thus T-304 is selected over T-430 where improved welding and cold forming ability is required. When improved welding, cold forming, and significantly better corrosion resistance is required, T-316 is selected over T-430. In a cost critical setting that can accept lower corrosion resistance, T-410L may be chosen over T-430.
