HS S350 Hot Work Die Steel

As one of responsible die steel suppliers, Hongsheng Group has been focusing on the development and production of special steel castings, forged barsand mechanical parts for more than 25 years. The company adheres to the principle of "pursuing excellence and building a world brand", and has passed ISO9001, ISO14001, OHSAS18001, got PED, API, CNAS certification, and approved by 8 membership of IACS.

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 H13 steel. It is widely used in die casting molds, hot extrusion dies, hot punching dies, hot forging dies, etc.
