We offer a broader choice of materials:

For wear application:
* High Speed Tool Steel : W6Mo5Cr4V2;

high speed tool steel:

1) High Speed Tool Steel, the steel has a high hardenability and thermal cracking resistance, the steel contains a higher content of tungsten,molybdenum,chromium and alum, good wear resistance, toughness is relatively weakened, with good heat resistance.
2) High hardness,Hardenallity HRC up to 65.

* PM-HIP material : SAM10,SAM26,SAM39,CPM10V,CPM9V

For corrosion application:
* Nitride Steel: 38CrMoAIA
* PM-HIP material : SAM26,SAM39,CPM10V,CPM9V

For wear and corrosion application:
* PM-HIP material : SAM26,SAM39,CPM10V,CPM9V

Other materials:
Stainless Steel: 316L ,C276 etc.

By working closely with customers in choosing optional materials, we can minimize wear and tear and associated costs.
