60WCrV8 Mould Steel Bar

 

60WCrV8 die steel is used to make a cold die mould, hot forging die mold and other steel. Mold is the main processing tool for manufacturing parts in the industrial sector such as machinery manufacturing, radio instrumentation, motor, electrical and other industrial parts. The quality of the mold directly affects the quality of the pressure processing technology, the accuracy of production and production costs, and mold quality and service life in addition to reasonable structural design and processing accuracy, mainly by the mold material and heat treatment. Mold steel can be divided into cold-rolled die steel, hot-rolled die steel and plastic mold steel three categories for forging, stamping, cutting, die-casting and so on.

 

As a result of various molds use different working conditions are complex, so the mold steel, according to the mold manufacturing conditions, should have a high hardness, strength, wear resistance, adequate toughness, and high hardenability, quenching Hard and other process performance. Because of these different uses, working conditions are complex, so the performance requirements for the mold steel is also different. Plastic molds include thermoplastics molds and thermosetting plastic molds.

 

Plastic mold steel with a certain strength, hardness, wear resistance, thermal stability and corrosion resistance and other properties. In addition, it also requires a good process, such as heat treatment becomes smaller, good processing performance, good corrosion resistance, grinding and polishing performance, good welding performance, high roughness, good thermal conductivity and working conditions, size and shape stability The Under normal circumstances, injection molding or extrusion die can be used hot work die steel; thermosetting forming and demanding high wear resistance, high strength mold can be used cold work die steel.
