What material is skd6 1?

Hot working die steel is a kind of steel formed by adding alloying elements on the basis of carbon steel, which can be used for die forging, aluminum alloy die casting, hot extrusion die, high-speed precision forging die and forging die.

If hot-working die steel is subdivided into die-casting die steel, hot-forging die steel and hot-extrusion die steel, ordinary hot-working die steel is not qualified for high-grade die-casting die, but high-grade die-casting die steel can be used for low-grade hot-working die, and there is a huge difference in characteristics and price between them.

Main features:

(1) has high hardenability, and the medium with small cooling intensity and small heat treatment deformation can be used for heat treatment;

(2) It has high thermal cracking resistance and thermal fatigue resistance, so that the mold is not easy to form cracks when it is chilled and heated, and the cracks formed are not easy to spread, thus avoiding the failure of the mold;

(3) It has high thermal softening resistance and high-temperature wear resistance, so that the mold maintains a certain high-temperature strength and dimensional stability;

(4) The heat treatment deformation is small;

(5) Medium and high cutting performance;

(6) Moderate decarbonization resistance.
