Metal stamping mould material performance standards
1 manufacturability, annealing of spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high.
2, 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.
3 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.
4, cutting machining cutting dosage, low dissipation of cutting tool and the processing surface roughness is low.
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, can grinding wheel relatively small loss, no limit of large amount of grinding burns, insensitive to the quality of grinding wheel and cooling conditions, not easy to happen grinding and grinding cracks.
8 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, the quenching temperature and shape of the workpiece is not exclusive.
Metal stamping factory production mold to exempt from the mold design.
