EN 1.4913 (X19CrMoNbVN11-1) Stainless Steel

EN 1.4913 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. 1.4913 is the EN numeric designation for this material. X19CrMoNbVN11-1 is the EN chemical designation.

It has a moderately high embodied energy and can have a moderately high tensile strength among wrought martensitic stainless steels.

The properties of EN 1.4913 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 1.4913 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 1.4913 stainless steel is notable for including boron (B) and vanadium (V). Boron is used to improve hardenability. It has a substantial effect when added in even tiny amounts. It can also facilitate sintering. Vanadium has a strong hardening effect, but this effect is particularly sensitive to the type of tempering.

Iron (Fe) 84.5 to 88.3
Chromium (Cr) 10 to 11.5
Manganese (Mn) 0.4 to 0.9
Molybdenum (Mo) 0.5 to 0.8
Nickel (Ni) 0.2 to 0.6
Niobium (Nb) 0.25 to 0.55
Silicon (Si) 0 to 0.5
Carbon (C) 0.17 to 0.23
Vanadium (V) 0.1 to 0.3
Nitrogen (N) 0.050 to 0.1
Phosphorus (P) 0 to 0.025
Aluminum (Al) 0 to 0.020
Sulfur (S) 0 to 0.015
Boron (B) 0 to 0.0015
