# Cold Drawn (+U+C) 1.0314 Steel

EN 1.0314 +U+C steel is EN 1.0314 steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare EN 1.0314 +U+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.
