H950 Hardened S45503 Stainless Steel
H950 hardened S45503 stainless steel is S45503 stainless steel in the hardened (H) condition. The graph bars on the material properties cards below compare H950 hardened S45503 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.
