XD15NW Steel
Steel name: XD15NW
Diagram No.: 2244
Mat.No. (Wr.Nr.) designation: 1.4123
DIN designation: X40CrMoVN16-2
UNS designation: S42025
Chemical composition in weight %: 0.37-0.45% Mn, max. 0.60% Si, max. 0.60% Mn, 15.00-16.50% Cr, 1.50-1.90% Mo, max. 0.30% Ni, 0.20-0.40% V, 0.16-0.25% N
Steel group: Martensitic steels
Properties: For high stress applications, like bearings, the required hardness is at least 58 HRC. The choice of stainless grades then becomes rather limited. The most common grade is X105CrMo17 and the associated compositions with slight variations of carbon, chromium or molybdenum. Addition of other elements like tungsten, vanadium and niobium can be made in order to improve the temperature resistance. However, for all these grades, the carbon content gives the required hardness and has to be kept at a minimum of 0.7 % to yield 58 HRC.
Applications: Bearings (ball, roller, spherical). Ball and roller-screws. Rod ends.
Reference: Not shown in this demo version.
Heat Treatment
Hardening: 980 °C and 1080 °C, gas or oil cooling.
