In an acidic medium white cast iron with w(Cr) = 28% has much better wear resistance and high-temperature oxidation resistance than a white cast iron with w(Cr) = 15%. The C-content of this white cast iron can vary between w(C) = 2.0 – 3.3%, increasing the Cr-content and reducing the C-content can improve its corrosion and abrasion resistance.
