As one of responsible die steel suppliers, Hongsheng Group has been focusing on the development and production of special steel castings, forged bars and 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 steel is 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.
Chemical properties of HS S350
Steel Grade | C | Si | Mn | Cr | P | S | V | Mo |
HS S350 | 0.35~0.40 | 0.10~0.30 | 0.40~0.60 | 4.90~5.40 | ≤0.015 | ≤0.002 | 0.40~0.65 | 1.80~1.90 |
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
l As one of die steel manufacturers, 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.
l High temper softening resistance, thermal fatigue resistance, thermal melting loss resistance., etc.
l High impact toughness and high isotropy.
