Die casting steel is the steel used to make cold stamping dies, hot forging dies, die casting dies and other dies. In industries such as machinery manufacturing, radio equipment manufacturing and motor manufacturing, moulds are the main tool for processing parts. Die-casting die quality directly affects the quality of the die-casting process, product accuracy yield and production costs, and die quality and service life in addition to rely on reasonable structural design and processing accuracy, but also mainly by the impact of die materials and heat treatment.

Mould casting steel mainly has cold rolled mould casting steel, hot rolled mould casting steel and plastic mould casting steel three, respectively for forging, stamping, cutting, die-casting, etc.. Different mold use, working conditions are complex, for the import of hot mold steel, should be based on its manufacturing mold working conditions require high hardness, strength, wear resistance, sufficient toughness, high quenchability, quenchability and other process properties. This cold work mould steel material use is different, the working conditions are complex, the performance requirements of the steel for moulds are also different. It mainly includes cold pressing moulds, stretching moulds, embossing moulds, friction moulds, roller plates, cold pressing moulds, cold pressing moulds, etc.
