EN 1.4589 (X5CrNiMoTi15-2) Stainless Steel

EN 1.4589 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4589 is the EN numeric designation for this material. X5CrNiMoTi15-2 is the EN chemical designation.

It has a fairly high tensile strength and a fairly low ductility among wrought ferritic stainless steels.

The graph bars on the material properties cards below compare EN 1.4589 stainless steel to: wrought ferritic 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.
