Principal Component Ratio(mass%)

Applications:Widely used in the manufacture of semiconductor products, ultra-high vacuum valve devices, filter housings and other stainless steels that require ultra-clean and ultra-low gas components.

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