Wear resistance High-speed and Tool steel

The M series high speed steel grades M2 and M3/2 are the most widely used tool steel alloys for PM wear applications. In these materials the alloying elements C, Cr, Mo, V, and W combine to give a carbide structure and strengthened matrix for excellent wear resistance and high temperature properties.

OB1 is a powder grade that cost-efficiently combines wear resistance and thermal softening resistance by combining Cr as the main carbide forming element and relatively small amounts of the more expensive carbide forming elements W, Mo and V. The powder grade HCx combines significant wear resistance with a high degree of corrosion resistance. Carbon and the strong carbide forming elements W, Mo, V and Cr produce a uniform dispersion of hard wearing carbides after sintering. The level of Cr ensures stainless corrosion resistance.
