The heat treatment process must reach these eight realms!
1, divided into two: different materials, different equipment, different process parameters, heat treatment after the organization and quality are also different. Even if the material grade, equipment, process parameters are the same, due to the chemical composition content of the upper and lower limits, heat treatment temperature upper and lower limits, holding time upper and lower limits are different, the organization and quality after heat treatment will be different. Even if the upper and lower limits of chemical composition content, the upper and lower limits of heat treatment temperature and the upper and lower limits of holding time are the same, the organization and quality after heat treatment will also be different due to the different processes, quality and organization of cold and hot processing in the early stage of heat treatment. Therefore, after the problem to specific problems specific analysis, that is, to be divided into two
