EN 1.4110 (X55CrMo14) Stainless Steel

EN 1.4110 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 1.4110 is the EN numeric designation for this material. X55CrMo14 is the EN chemical designation.

It can have a moderately low ductility among the wrought martensitic stainless steels in the database.

The properties of EN 1.4110 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 1.4110 stainless steel to: wrought martensitic 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.
