Commonly used material types of jaw plate of jaw crushe
r
1. High manganese steel: It is the traditional material of the jaw plate
of the jaw crusher. It has good toughness and good deformation hardening ability.
2. Medium manganese steel: Due to the low initial hardness and low yield strength of high manganese steel, under non-strong impact conditions, its hardening is insufficient, and it is easy to rheology and cut. In order to improve the service life of the jaw plate, medium manganese steel was developed.
3. High-chromium cast iron and high-manganese steel composite: Although high-chromium cast iron is an excellent
wear-resistant material, due to its poor toughness, when it is impacted or squeezed by the material, it will directly crack or
deform a few times. flaking.
4. Low alloy cast steel: Medium carbon low alloy cast steel is currently widely used.
