Material and function of jaw crusher side plate

The materials of the jaw crusher side plate mainly include high manganese steel, medium manganese steel, high chromium cast iron and medium carbon low alloy cast steel. ‌

 

Material selection ‌High manganese steel‌: High manganese steel is the traditional Jaw Plate material with good impact load resistance, but due to the large opening angle between the dynamic and fixed jaw plates, it is easy to cause abrasive sliding, low surface hardness and rapid wear‌. ‌Medium manganese steel‌: Medium manganese steel improves wear resistance and toughness by reducing manganese content and adding other elements (such as chromium, silicon, etc.). The service life is more than 20% higher than that of high manganese steel, and the cost is equivalent‌12. ‌High chromium cast iron‌: High chromium cast iron has high wear resistance, but poor toughness. It is usually used in combination with other materials to improve wear resistance and toughness‌. ‌Medium carbon low alloy cast steel‌: This material has high hardness and moderate toughness, can resist material cutting and extrusion, and has a service life more than 3 times higher than that of high manganese steel‌12. Functions and characteristics of materials

‌High manganese steel‌: has good impact resistance and deformation hardening ability, but the surface hardness is low and easy to wear. ‌Medium manganese steel‌: improves wear resistance by inducing martensitic phase transformation through deformation, while maintaining high toughness. ‌High chromium cast iron‌: high wear resistance, but poor toughness, usually used in combination with other materials to improve comprehensive performance. ‌Medium carbon low alloy cast steel‌: has high hardness and moderate toughness, and can resist cutting and extrusion of materials. ‌Advantages and disadvantages of materials and applicable scenarios ‌High manganese steel‌: suitable for working conditions with large impact loads, but wears faster. ‌Medium manganese steel‌: suitable for small and medium-sized jaw crushers, with good wear resistance and toughness. ‌High chromium cast iron‌: suitable for working conditions requiring high wear resistance, but the cost is high. ‌Medium carbon low alloy cast steel‌: suitable for various working conditions, with good wear resistance and toughness.
