XD16N Steel

Steel name: XD16N
Diagram No.: 2245
UNS designation: S42716
DIN designation: X50CrSiMnVN16-1
AMS designation: 5926
Chemical composition in weight %: 0.45-0.60% C, 1.30-1.70% Si, max. 0.80% Mn, 15.00-16.50% Cr, 0.20-0.40% Mo, max. 0.40% Ni, 0.20-0.40% V, 0.05-0.20% N
Steel group: Martensitic steels
Properties: Numerous applications require the use of stainless steels resisting high mechanical stresses combined with abrasive and corrosive environments. Besides some of these applications work at relatively high temperature. For industrial bearings, ball-screws and for certain tools, the required hardness (56 – 58 HRC min) combined with the need for hard carbides for wear resistance strongly limits the material choice. A very common grade used is AISI 440C / X105CrMo17 (XDBD), and associated compositions. Addition of W, V and Nb can be made to improve the temperature resistance. However, for all these grades, it is the carbon content that gives the required hardness and it has to be kept at a minimum of 0.7% to yield 58 HRC. For valve applications, commonly used solutions are 1.4748 – X85CrMoV18-2 (APZ9) with high sensitivity to quench cracking or 1.4718 – X45CrSi9-3 (SOS3) with very poor corrosion resistance.
Applications: Bearings, ball-screws for industrial applications, gears, valves, injection systems for automotive, cold work in corrosive environment.
