Cold Worked (+C700) 1.4541 Stainless Steel
EN 1.4541 +C700 steel is EN 1.4541 stainless steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare EN 1.4541 +C700 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.
