Die die heat treatment is to ensure that the important properties of the process. Its manufacture of precision molds, mold strength, the manufacturing cost of mold, mold of his working life has a direct impact. Based on the analysis of mold materials and heat treatment and metallographic 40Cr steel on an experimental basis, in accordance with the conditions of mold material, the nature of the sample material, as well as the 40Cr microstructure heat treatment technology and comprehensive analysis, based on the actual formulation of a reasonable heat treatment process, and According to an analysis of experimental data. In this way, make good use of mold performance and life requirements. At the same time, meet the requirements of the economy and reduce costs.
