4Cr5MoSiV1

Description

4Cr5MoSiV1 is a widely used air-cooled hardening hot work die steel. Compared with 4Cr5MoSiV, it has higher thermal strength, good toughness under medium temperature conditions, and has thermal fatigue performance and certain wear resistance when operating at **0 °C. Air quenching at a small austenitizing temperature, the heat treatment deformation is small, the oxidation tendency is small, and it can resist the erosion effect of molten aluminum. Good thermal crack resistance, copper melting in electroslag, dense structure, pure electric furnace refined steel, and good isotropic properties 


It is widely used in the manufacture of hot extrusion dies, mandrels, hammer dies for die forging hammers, die for forging presses, die casting dies for precision forging machines, and die-casting dies of aluminum and copper machine alloys. Suitable for large or complex shaped molds
