WebWhite iron is too brittle for use in many structural components, but with good hardness and abrasion resistance and relatively low cost, it finds use in such applications where wear resistance is desirable, such as on the teeth of excavators, impellers and volutes of slurry pumps, shell liners and lifter bars in ball mills.. For example, Ni-Cr-HC martensitic white … WebIn cast iron …cast iron is either so-called gray iron or white iron, the colours shown by fracture. Gray iron contains more silicon and is less hard and more machinable than is white iron. Both are brittle, but a malleable cast iron produced by a prolonged heat treatment was developed in France in… Read More In iron processing: Gray iron
