Precision mold satisfies the requirement of process performance eight precision mold manufacturing is typically after forging, machining, heat treatment, and a few procedure. To ensure the manufacturing quality of mould, reduce production cost, the materials should have good malleability, cutting machining, hardenability, hardenability and grinding; Also should have little oxidation and decarburization sensitivity quenching distortion and cracking tendency. 1, malleability has lower hot forging deformation resistance, good plasticity, forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low. 2 manufacturability, annealing of spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high. 3, large cutting machining cutting dosage, low dissipation of cutting tool and the processing surface roughness is low. 4 when heated to high temperature oxidation, oxidation and decarburization sensitivity bosom can good, decarbonization speed slow, is not sensitive to the heating medium, produce pitting tend to be small. 5, hardenability is uniform and high surface hardness after quenching. 6, hardenability after quenching can get deeper hardening layer, the ease of quenching medium can be hardened. 7 cracking tendency of conventional quenching, quenching deformation small volume change, shape warping, distortion mild, abnormal deformation tend to be low. Conventional quenching cracking sensitivity is low, is not sensitive to quenching temperature and shape of the workpiece. 8, can grinding wheel is relatively low dissipation, grinding dosage, no burn limit is not sensitive to the quality of grinding wheel and cooling conditions are less grinding and grinding cracks.
