Hardened (+H) 1.3532 Steel
EN 1.3532 +H steel is EN 1.3532 steel in the hardened (H) condition. It has the highest strength compared to the other variants of EN 1.3532 steel. The graph bars on the material properties cards below compare EN 1.3532 +H 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.
