# Cold Rolled 1.4482 Stainless Steel

Cold rolled EN 1.4482 is EN 1.4482 stainless steel in the cold worked (strain hardened) condition. The graph bars on the material properties cards below compare cold rolled EN 1.4482 to: wrought duplex stainless 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.
