H1000 Hardened S45503 Stainless Steel
H1000 hardened S45503 stainless steel is S45503 stainless steel in the hardened (H) condition. It has the lowest strength and highest ductility compared to the other variants of S45503 stainless steel.
The graph bars on the material properties cards below compare H1000 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.
