H1050 Hardened S13800 Stainless Steel

H1050 hardened S13800 stainless steel is S13800 stainless steel in the hardened (H) condition. The graph bars on the material properties cards below compare H1050 hardened S13800 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.
