EN 1.4150 (X53CrSiMoVN16-2) Stainless Steel
EN 1.4150 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4150 is the EN numeric designation for this material. X53CrSiMoVN16-2 is the EN chemical designation.
It has a moderately low electrical conductivity among wrought martensitic stainless steels. In addition, it has a moderately high embodied energy and a moderately low thermal conductivity.
The graph bars on the material properties cards below compare EN 1.4150 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.

Alloy Composition
Among wrought stainless steels, the composition of EN 1.4150 stainless steel is notable for including vanadium (V) and containing a comparatively high amount of silicon (Si). Vanadium has a strong hardening effect, but this effect is particularly sensitive to the type of tempering. Silicon content is typically governed by metallurgical processing concerns, but it can also be added for the purpose of improving oxidation resistance.
