EN 1.4035 (X46CrS13) Stainless Steel

EN 1.4035 stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4035 is the EN numeric designation for this material. X46CrS13 is the EN chemical designation.

It has a moderately low embodied energy among wrought martensitic stainless steels. In addition, it has a moderately high electrical conductivity and a moderately low tensile strength.

The graph bars on the material properties cards below compare EN 1.4035 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 1.4035 stainless steel is notable for containing comparatively high amounts of chromium (Cr) and manganese (Mn). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance. Manganese is used to improve ductility at elevated temperatures. It also permits a higher nitrogen content than would otherwise be possible.

Iron (Fe) 82.1 to 86.9
Chromium (Cr) 12.5 to 14
Manganese (Mn) 0 to 2.0
Silicon (Si) 0 to 1.0
Carbon (C) 0.43 to 0.5
Sulfur (S) 0.15 to 0.35
Phosphorus (P) 0 to 0.040

All values are % weight. Ranges represent what is permitted under applicable standards.
