Hot work die steel, used for
casting die steel, have higher strength and
hardness, resistance to thermal fatigue resistance is good, and has
good hardenability, but its toughness and plasticity is poor. For
the fabrication of high temperature, high stress, not by the convex
die, die of shock load, such as die-casting die, hot extrusion die,
precision forging die, non-ferrous metal forming
mold.
