EN 1.4962 (X12CrNiWTiB16-13) Stainless Steel
EN 1.4962 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. 1.4962 is the EN numeric designation for this material. X12CrNiWTiB16-13 is the EN chemical designation.
It has a moderately high base cost and can have a moderately low ductility among wrought austenitic stainless steels.
The properties of EN 1.4962 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 1.4962 stainless steel to: wrought austenitic 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 1.4962 stainless steel is notable for including boron (B) and tungsten (W). Boron is used to improve hardenability. It has a substantial effect when added in even tiny amounts. It can also facilitate sintering. Tungsten interacts with other alloying elements to a greater extent than usual, which makes it hard to broadly characterize its effects.
