# Hot Rolled 1.4662 Stainless Steel

Hot rolled EN 1.4662 is EN 1.4662 stainless steel in the hot worked condition. The graph bars on the material properties cards below compare hot rolled EN 1.4662 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.
