Quenched and Tempered (+QT) 1.4913 Stainless Steel
EN 1.4913 +QT steel is EN 1.4913 stainless steel in the quenched and tempered condition. The graph bars on the material properties cards below compare EN 1.4913 +QT steel to: wrought martensitic 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.
