- Steel alloy with a min. of 10.5% Cr for corrosion resistance
- Passivation layer of Cr2O3 formed by addition of min. of 10.5% Cr
- Addition of various components of Ni, Mo, N for improving corrosion resistance and workability Typically 13Cr steel, 18Cr-8Ni steel, Main component Cr forms very think Cr2O3 layer blocking further diffusion of oxygen into the base metal.
