Normalized (+N) 1.1165 Cast Steel
EN 1.1165 +N steel is EN 1.1165 cast steel in the normalized condition. It has the lowest strength and highest ductility compared to the other variants of EN 1.1165 cast steel. The graph bars on the material properties cards below compare EN 1.1165 +N steel to: cast carbon 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.
