High Shearability (+S) 1.5024 Steel
EN 1.5024 +S steel is EN 1.5024 steel in the shearability treated condition. The graph bars on the material properties cards below compare EN 1.5024 +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.
