4Cr5MoSiV mould steel features and application:
4Cr5MoSiV grade steel has good toughness, heat strength and thermal fatigue properties and can be air-cooled and hardened. The air quenching is performed at a lower austenitizing temperature, the heat treatment deformation is small. The scale of the scale generated during the air quenching is small, and the erosion resistance of the molten aluminum can be resisted. The production of aluminum die-casting molds, hot extrusion die and perforated mandrel, plastic film and so on.
