What About the PM Tool Steel Ralloy WR13

Ralloy® WR13 is an extra high chromium alloyed P/M-tool steel. Due to high volume of fine uniformly distributed hard carbides it has an excellent wear resistance with good toughness. The very high chromium content ensures good corrosion resistance in operation environment.

Due to high volume of hard chromium, vanadium and niobium carbides and the uniform fine microstructure the abrasion resistance of WR13 is superior to conventional stainless wear resistant steels and most PM-tool steels. The high chromium level in the matrix results in excellent corrosion resistance.
