The initial hardness of high manganese steel is very low, only 220-250 HV, but the characteristic of high manganese steel is that the harder it is worn, the harder it is, and the hardness can reach 600 HV after a period of use.
The wear-resistant method of high-manganese steel is required. 1. The initial hardness is high. 2. Let the working thickness of high-manganese steel increase so that his wear-resistant strength can be exerted.
Manganese steel is a relatively soft material, its initial hardness is about 220-250 HV, the depth of the impact hardening layer is between 10-15 mm, and the hardness in coarse crushing can reach 600 HV. In fine crushing applications, the impact hardening layer is thinner, and the hardness is usually around 350-500 HV.
The most reliable way to check the wear resistance of high manganese steel is the metallographic inspection of the finished product and after heat treatment. Ordinary chemical composition can only indicate physical and chemical indicators. The mechanical properties cannot be prepared to explain his wear resistance. At most, it is an initial hardness index that can be referenced
Heat treatment is another key step to ensure high-toughness and high-quality castings. The shape of the crushing chamber has a significant impact on the operating performance of the crusher and the service life of the wear parts.
