HS S350 Hot Work Die Steel
HS S350 steelis improved Cr-Mo-V hot work die steel. The special composition design makes it have high high-temperature strength and thermal fatigue resistance. The overall performance is better than traditional H13steel. It is widely used in die casting molds, hot extrusion dies, hot punching dies, hot forging dies, etc.

Application of HS S350
Suitable for medium and large molds of die-casting, hot forming, hot forging, hot extruding with aluminum/magnesium material.
Features of HS S350
As one of die steel suppliers, we provide this kind of hot work die steel, whose hardness after heat treatment is comparable to that of SUPER H13 steel, while the toughness and polishing performance are more than twice of H13.
High temper softening resistance, thermal fatigue resistance, thermal melting loss resistance., etc.
High impact toughness and high isotropy.
