Precision Mold manufacturing is the bottleneck and key to restrict the development of China's automobile, household appliances, light industry and other industries. With the continuous development and improvement of rapid prototyping hardware and software equipment and rapid prototyping materials, the strength and precision of rapid prototyping parts have been continuously improved. High-quality, high-precision molds are inseparable from our high requirements for material properties. According to the requirements of mold manufacturing on material performance, the details are as follows: 1. Annealing process spheroidizing annealing temperature range is wide, annealing hardness is low, fluctuation range is small, and spheroidizing rate is high. 2. Forgeability has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of forging crack cold crack and precipitation of reticular carbide. 3. Oxidation and decarburization sensitivity when heated at high temperature, it has good oxidation resistance, slow decarburization speed, insensitivity to heating medium, and small tendency to generate pitting. 4. Machinability, large cutting parameters, low tool loss and low surface roughness. 5. Hardened after quenching, it has uniform and high surface hardness. 6. After hardenability quenching, a deeper hardened layer can be obtained, which can be hardened by using mild quenching medium. 7. The grindable grinding wheel has small relative loss, large limit grinding capacity without burns, insensitivity to the quality and cooling conditions of the grinding wheel, and is not easy to cause abrasion damage and grinding cracks. 8. Quenching deformation and cracking tendency conventional quenching volume changes little, shape warpage and distortion are slight, and abnormal deformation tendency is low. Conventional quenching has low cracking sensitivity and is not sensitive to quenching temperature and workpiece shape.
