EN 1.4983 (X6CrNiMoTiB17-13) Stainless Steel
EN 1.4983 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the solution annealed (AT) condition. 1.4983 is the EN numeric designation for this material. X6CrNiMoTiB17-13 is the EN chemical designation.
The graph bars on the material properties cards below compare EN 1.4983 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 1.4983 stainless steel is notable for including boron (B) and titanium (Ti). Boron is used to improve hardenability. It has a substantial effect when added in even tiny amounts. It can also facilitate sintering. Titanium is used to broadly improve mechanical properties.
