Hot work die casting mould steel

Hot work die casting mould steel

Hot work mould steel refers to alloy tool steel suitable for making moulds for hot deformation processing of metal, such as hot forging mould, hot extrusion mould, die casting mould, hot heading mould, etc.. Hot work mould steel in the work withstand great impact, mould cavity and high temperature metal contact, repeated heating and cooling, its use conditions are extremely harsh. In order to meet the requirements of the use of hot work mould, hot work mould steel should have the following basic characteristics: (1) high temperature strength and good toughness. Hot work die, especially hot forging die, work with great impact, and 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, due to hot work mould ding work in addition to frictional wear generated by the blank deformation, but also subject to high temperature oxidation corrosion and oxidation of iron filings of grinding, so the need for hot work m…
