Product Introduction

High manganese steel lining plate, hammer head, screen, jaw plate, etc. are the most widely used steel casting parts in cement plants at present, it has high wear resistance, good toughness and economy

Well received.

First, the characteristics of high manganese steel: high manganese steel has good plasticity and impact toughness, the surface of the hardened layer under the impact of external force, the hardened surface layer is worn

Later, new surface layers appear and continue to be work hardened. Therefore, high manganese steel castings have high surface wear resistance, and the inside part still retains the original mechanical properties. Due to the

for

High manganese steel has the above characteristics, so at present, there is no wear-resistant material in the world can completely replace high manganese steel.
