White iron castings for abrasion resistance

White iron castings deliver long wear life in the harshest environments. With very high surface hardness and proven abrasion resistance, they’re ideal for agricultural ground-engaging parts, mining equipment, and other high-wear applications. We offer multiple grades including high chromimum for tailored protection.

    Why choose white iron?

    White iron is selected for its hardness and ability to withstand harsh, abrasive conditions. It’s the material of choice where extended wear life is critical and impact loads are minimal.
