EN 1.4062 (X2CrNiN22-2) Stainless Steel

EN 1.4062 stainless steel is a duplex stainless steel formulated for primary forming into wrought products. 1.4062 is the EN numeric designation for this material. X2CrNiN22-2 is the EN chemical designation.

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

The properties of EN 1.4062 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 1.4062 stainless steel to: wrought duplex 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 1.4062 stainless steel is notable for containing a comparatively high amount of chromium (Cr). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance.

Iron (Fe) 69.3 to 77.3
Chromium (Cr) 21.5 to 24
Nickel (Ni) 1.0 to 2.9
Manganese (Mn) 0 to 2.0
Silicon (Si) 0 to 1.0
Molybdenum (Mo) 0 to 0.45
Nitrogen (N) 0.16 to 0.28
Phosphorus (P) 0 to 0.040
Carbon (C) 0 to 0.030
Sulfur (S) 0 to 0.010
