Annealed (+A) 1.3563 Steel
EN 1.3563 +A steel is EN 1.3563 steel in the annealed condition. It has the lowest strength compared to the other variants of EN 1.3563 steel. The graph bars on the material properties cards below compare EN 1.3563 +A 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.
