· Two of the most commonly poured high chrome white iron alloys are Class II Type B (15% Cr) and Class III Type A (25% Cr). The higher the amount of chromium dissolved in the matrix of the metal, the greater the corrosion resistance. Consequently, a Class III Type A (25% Cr) would be the better choice for corrosive environments such as
