Hardened 410 Stainless Steel
Hardened AISI 410 is AISI 410 stainless steel in the hardened (H) condition. The graph bars on the material properties cards below compare hardened AISI 410 to: wrought martensitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
