Precipitation Hardened (+P1200) 1.4530 Stainless Steel
EN 1.4530 +P1200 steel is EN 1.4530 stainless steel in the aged (precipitation hardened) condition. The graph bars on the material properties cards below compare EN 1.4530 +P1200 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.
