EN 1.4482 (X2CrMnNiMoN21-5-3) Stainless Steel
EN 1.4482 stainless steel is a duplex stainless steel formulated for primary forming into wrought products. 1.4482 is the EN numeric designation for this material. X2CrMnNiMoN21-5-3 is the EN chemical designation.
It has a moderately low base cost among wrought duplex stainless steels. In addition, it has a moderately high ductility and a moderately low embodied energy.
The properties of EN 1.4482 stainless steel include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN 1.4482 stainless steel 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.

Alloy Composition
Among wrought stainless steels, the composition of EN 1.4482 stainless steel is notable for containing a comparatively high amount of manganese (Mn) and including copper (Cu). Manganese is used to improve ductility at elevated temperatures. It also permits a higher nitrogen content than would otherwise be possible. Copper is used to improve resistance to acids, and to improve formability.
