EN 1.4982 (X10CrNiMoMnNbVB15-10-1) Stainless Steel
EN 1.4982 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the warm worked condition. 1.4982 is the EN numeric designation for this material. X10CrNiMoMnNbVB15-10-1 is the EN chemical designation.
It has a moderately low thermal conductivity among wrought austenitic stainless steels. In addition, it has a fairly high embodied energy and a moderately high base cost.
The graph bars on the material properties cards below compare EN 1.4982 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 1.4982 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.
