Product material
Alloy 410 (UNS S41000) is a 12% chromium martensitic stainless steel that can be heat treated to obtain a wide range of mechanical properties. The alloy has good corrosion resistance along with high strength and hardness. In the annealed condition, 410 stainless steel is ductile and may be formed. It remains magnetic in both the annealed and heat treated conditions.
