H1100 Hardened S45000 Stainless Steel
H1100 hardened S45000 stainless steel is S45000 stainless steel in the hardened (H) condition. The graph bars on the material properties cards below compare H1100 hardened S45000 stainless steel to: wrought precipitation-hardening 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.
