EN 1.4516 (X6CrNiTi12) Stainless Steel

EN 1.4516 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4516 is the EN numeric designation for this material. X6CrNiTi12 is the EN chemical designation.

It has a fairly high thermal conductivity among wrought ferritic stainless steels. In addition, it has a moderately low base cost and a moderately low embodied energy.

The graph bars on the material properties cards below compare EN 1.4516 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.
