Mine steel is the most popular and focused steel products on the market today. It is the key steel products that our company has provided for the market all year round, our company is also familiar with the basic maintenance skills of miner steel, the reasons for the cracking of the miner's steel in the process of tempering are summarized.

In general, the presence of component segregation, gas and inclusions, and forging temperature and forging ratio are not properly mastered, there are more problems. Because the raw material of miner steel often has the ribbon segregation, after the thermal pressure processing, there is still a component segregation, this segregation can be seen from anneal tissue after quenching. And it’s because of segregation, it is only in the oxidizing atmosphere that the miner's steel is heated close to the solid line, it is easy to produce precipitates or impurities, the main cause of the defect.

Studied have shown that, miners steel because of forging process, heat treatment process and other problems, the mixed tissue and complex stress distribution were obtained after quenching, it can cause cracking. For brittle artifacts, it is better to use the controllable gas multi-purpose furnace for isothermal quenching, high temperature tempering and so on, the effect will be more stable.
