Hardened (+H) 1.1192 Steel
EN 1.1192 +H steel is EN 1.1192 steel in the hardened (H) condition. It has the highest strength compared to the other variants of EN 1.1192 steel. The graph bars on the material properties cards below compare EN 1.1192 +H steel to: wrought carbon or non-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.
