Hot work die casting mould steel

Hot work die casting mould steel Hot Work Die Casting Mould Steel refers to alloy tool steel suitable for making metal hot deformation processing molds, such as hot forging molds, hot extrusion molds, die casting molds, hot upsetting molds, etc. Thermal model steel is subjected to great impact in the work, the mold cavity is in contact with high temperature metal, repeated heating and cooling, and its use conditions are extremely harsh. In order to meet the requirements of hot work molds, hot work die steel should have the following basic characteristics: (1) High temperature strength, good toughness. Thermal dies, especially hot forging dies, are subject to great impact when working, and the impact frequency is very high, if the die does not have high strength and good toughness, it is easy to crack. (2) Good wear resistance, because the hot working die will cause friction and wear in addition to the deformation of the blank, it will also be subjected to high temperature oxidation co…
