EN 1.4570 (X6CrNiCuS18-9-2) Stainless Steel

EN 1.4570 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 1.4570 is the EN numeric designation for this material. X6CrNiCuS18-9-2 is the EN chemical designation.

It has a moderately high electrical conductivity among the wrought austenitic stainless steels in the database.

The graph bars on the material properties cards below compare EN 1.4570 stainless steel to: wrought austenitic 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.
