Aisi 410
AISI 410 / 410S (UNS S41008, 1.4000) is a martensitic stainless steel with 12% chromium for general purpose. The addition of a low carbon and small alloy minimizes austenite formation at high temperatures that restrict the hardening of the alloys. The AISI 410S remains soft and ductile even when cooled rapidly above the critical temperature.
