Application: Widely used in the manufacture of semiconductor products, ultra-high vacuum valve devices, filter housings, nuclear power, military and other super-corrosion, super-critical environments that require ultra-cleanliness and super corrosion resistance.

Key Technology: special smelting of VIM+VAR is used to reduce "non-metallic inclusion & gas composition "  in the production of materials .
