Hot Worked Steel

Hot working die steel
It can resist the corrosion of molten aluminum, magnesium and zinc and the change of heat. It is suitable for the production of aluminum, magnesium and zinc alloy die-casting aluminum extrusion or hot-casting work, plastic reamer, grooving knife and hot forging punch. Because it adds chromium, molybdenum and vanadium, it has strong thermal toughness and can withstand high temperature and is not easily deformed.
