Good wear resistance of wear-resistant cast iron

- Sep 21, 2020-

Wear-resistant cast iron refers to cast iron with high hardness and high wear resistance under certain wear conditions. Its structure has uniform high hardness and wear resistance.

Cast iron has good wear resistance. Although its mechanical properties are worse than steel, it is more brittle and easy to break, but under the same conditions, it has a lower cost than steel. If the corresponding design and process are adopted, different requirements can be met under certain conditions, so it is widely used as a wear-resistant material for friction pairs. Especially when the friction pair requires both high wear resistance and good anti-friction properties, it is often more advantageous to use cast iron than steel. For example, parts such as machine tool rails, piston rings, and cylinder liners are mainly made of wear-resistant cast iron.
