Annealed (+A) 1.1219 Steel

EN 1.1219 +A steel is EN 1.1219 steel in the annealed condition. The graph bars on the material properties cards below compare EN 1.1219 +A 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.
