Warm Worked (+WW) 1.4962 Stainless Steel

EN 1.4962 +WW steel is EN 1.4962 stainless steel in the warm worked condition. The graph bars on the material properties cards below compare EN 1.4962 +WW steel to: wrought austenitic 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.
