Quenched and Tempered (+QT2) 1.5410 Cast Steel
EN 1.5410 +QT2 steel is EN 1.5410 steel in the quenched and tempered condition. It has the highest strength and lowest ductility compared to the other variants of EN 1.5410 steel. The graph bars on the material properties cards below compare EN 1.5410 +QT2 steel to: cast alloy 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.
