What are the attributes of precision stamping die materials? 'Hardware'

Precision stamping parts molds are equipment that must be used for stamping processing. The quality of molds has a major relationship with the workpiece. Therefore, the manufacturing requirements for precision molds are very strict. In order to ensure the quality of the molds, it can also reduce production costs. The materials for mold making It should have certain properties. Forgeability: low hot forging deformation resistance, good plasticity for precision stamping parts, wide forging temperature range, low forging cold cracking and low tendency to precipitate network carbides. Machinability: large cutting amount, low tool loss, and low surface roughness. Annealing processability: wide spheroidizing annealing temperature range, low annealing hardness and small fluctuation range, high spheroidizing rate. Hardenability: uniform and high surface hardness after quenching. Hardenability: After quenching, a deeper hardened layer can be obtained, and it can be hardened by using mild quenching medium. Grindability: The grinding wheel is relatively low in wear, and the amount of grinding is large without limit. It is not sensitive to the quality of the grinding wheel and the cooling conditions, and does not cause abrasion and cracks in the grinding precision stamping parts. Sensitivity to oxidation and decarburization: when heated at high temperature, it has good oxidation resistance, slow decarburization speed, insensitivity to heating medium, and little tendency to produce pitting. The manufacturing of the mold goes through processes such as forging, cutting and heat treatment. The processing difficulty is relatively high, and the requirements for manufacturing materials are high. It should have good processing performance to ensure that there are no process defects in the manufacturing process of precision stamping parts and the quality is stable.
