Spheroidized and Cold Drawn (+AC+C) 1.1192 Steel

EN 1.1192 +AC+C steel is EN 1.1192 steel in the spheroidized and cold-drawn condition. The graph bars on the material properties cards below compare EN 1.1192 +AC+C 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.
