Normalized and Tempered (+NT) 1.0625 Steel
EN 1.0625 +NT steel is EN 1.0625 steel in the normalized and tempered condition. The graph bars on the material properties cards below compare EN 1.0625 +NT 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.
