Material introduction of die spring

Characteristics of various die materials
As the mold is widely used and the working conditions of various molds are very different, the range of materials used for mold manufacturing is very wide, Die steel is the most widely used die material. It can be divided into cold working die steel, hot working die steel and powder high alloy die steel from M-type carbon structural steel, carbon tool steel, alloy structural steel, spring steel, high-speed tool steel, stainless and heat-resistant steel, to martensitic aging steel, powder high-speed steel, powder high-alloy die steel and so on Three types of mould steel for plastic forming

1. Cold working die steel
Cold working die steel is mainly used to manufacture the dies for pressing and forming workpieces in cold state, such as cold blanking die, cold stamping die, cold drawing die, embossing die, cold extrusion die, thread pressing die and powder pressing die, From all kinds of carbon tool steel, alloy tool steel, high speed tool steel to powder high speed tool steel and powder high alloy die steel

2. Hot working die steel
Hot work die steel is mainly used to manufacture die for high temperature work pieces, such as hot forging die, hot extrusion die, die casting die, hot upsetting die, etc. the commonly used hot work die steel includes: alloy die steel with medium and high carbon content and alloy elements such as Cr, W, Mo, V; for special requirements, hot work die steel is sometimes made of high alloy austenitic heat-resistant die steel

3. Steel for plastic mould
Because there are many kinds of plastics, the requirements for plastic products are very different, and different performance requirements are also put forward for the materials for making plastic moulds, Many industrial developed countries have formed a wide range of plastic mold steel series, including carbon structural steel, carburized plastic mold steel, pre hardened plastic mold steel, age hardening plastic mold steel, corrosion resistant plastic mold steel, easy cutting plastic mold steel, integral hardened plastic mold steel, maraging steel and mirror polishing plastic mold steel
