. Pelletizing dies made from tools steel are used in under water polymer pelletizers.

Pelletizing dies made from tools steel such as D2 (12% chromium) and H-13 ( 5% chromium) are used in under water polymer pelletizers. These steels provide abrasion resistance and withstand general wear from a cutting knife sliding over the surface at high speeds. A tungsten carbide finished coating layer of just .010” (surface ground and polished) can provide three times the wear resistance compared to these tool steels. In some cases it is possible to recoat a worn die or simply grind away the wear groove and continue using a tungsten carbide coated surface.
