NC22DNb is nickel-chromium-molybdenum alloy with niobium added. This provides high strength without a strengthening heat treatment. The alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion
We could delivery NC22DNb forging material as per the standard of EN
We use EAF+VOD-ESR melting methods to melt the material of NC22DNb
As per heat treatment of NC22DNb forged parts, We could do solution treatment and ageing treatment together.
The chemical composition of NC22DNb is as follows:
