Mar 18, 2026
Leave a message
AISI 410 is a straight chromium martensitic stainless steel with 11.5-13.5% chromium content, providing excellent corrosion resistance in mild environments. The martensitic microstructure develops through controlled cooling from austenitic temperatures, resulting in high strength and hardness capabilities.
