Overview of 1.2738 die steel

      1.2738 die steel It is a kind of pre hardened plastic die steel, which adopts advanced refining technology of die steel and is Cr Ni Mo alloy steel melted in vacuum. This kind of steel has good polishing, light etching, machinability and wear resistance; large mold does not need heat treatment, because it does not have the risk of quenching crack and heat treatment deformation; the mold must be softened and annealed before quenching, and tempered in time after quenching, and slowly heated. Cooling, grinding and machining should be paid attention to when the tempering die is grinded, otherwise the surface will soften and produce grinding cracks.

This kind of steel pre hardened steel has excellent polishing property, which is usually polished with alumina / gypsum. So how to polish it? At first, we first rough polishing, then more and more fine abrasive polishing, pay attention to every change of abrasive polishing, its direction must be changed, and the final polishing time should not be too long, otherwise it will affect the roughness of the mold surface. The corrosion resistance and wear resistance of the surface are increased. Although 1.2738 die steel has been pre hardened, heat treatment can be used to improve the hardness.
