SWHD High Wear Resistant Hot Working Die Steel
Product Details
Product Features
Based on Cr-Mo-V hot working die steel, the microalloying of Ni, Nb, etc. improves its high temperature toughness, high temperature hardness, thermal stability, thermal fatigue resistance and other properties, which greatly increases the heating temperature of the die surface.
Product Application
Suitable for hot extrusion punch dies, hot extrusion dies, precision forging dies, upsetting dies and hot extrusion punches.
