High Shearability (+S) 1.3515 Steel
EN 1.3515 +S steel is EN 1.3515 steel in the shearability treated condition. It has the second highest strength compared to the other variants of EN 1.3515 steel. The graph bars on the material properties cards below compare EN 1.3515 +S steel to: EN wrought 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.
