Forged Hot Work Alloy Tool Steel Din1.2344,H13,SKD61,4Cr5MoSiV1 Steel Round Bar
forged hot work alloy tool steel Din1.2344,H13,SKD61,4Cr5MoSiV1 steel round bar
1.H13 corresponding to AISI steel H13, is a widely used international air cooling hardening hot work die steel,
2 having a higher thermal strength and hardness, and has good toughness in the temperature conditions, the thermal fatigue properties and wear resistance,
3.Lower austenitizing temperature air quenching, heat deformation small, when the air quenching the small oxide tendencies, can resist the erosion of the role of the molten aluminum.
4.The steel is widely used in the manufacture of hot extrusion die, mandrel, forging hammer die, die forging presses, forging machine die-casting mold mold as well as aluminum, copper and its alloys.
