Mold steel which belongs to the steel?

 

Mold steel generally can be divided into "cold work die steel," "hot die steel" and "plastic mold steel" three categories. Mainly used for forging, stamping, cutting type, die-casting and so on. Due to different purposes, the working conditions are complex, so the performance requirements of the mold steel is also different.

 

1, cold work die steel: generally belong to the high-carbon alloy steel, carbon content of more than 0.80%, chromium is an important alloying element of such steel, its composition is usually not more than 5%. But for some high wear resistance requirements, small deformation after quenching mold, the maximum chromium content of up to 13%, commonly used steel with high carbon low alloy steel, high carbon high chromium steel, chromium molybdenum steel, medium carbon chromium tungsten Steel and so on.

2, hot work die steel: generally belong to the carbon steel, carbon content of 0.30% ~ 0.60%, belong to the sub-eutectoid steel, but also part of the steel due to join more alloy elements such as tungsten, molybdenum, vanadium and so on. Commonly used steel chromium-manganese steel, chrome-nickel steel, chromium tungsten steel.

3, plastic mold steel: plastic mold steel requires a certain degree of strength, hardness, wear resistance, thermal stability and corrosion resistance and other properties. In addition, also requires good processability, such as smaller heat treatment, good processing performance, good corrosion resistance, good grinding and polishing performance, good welding properties, high roughness, good thermal conductivity and working conditions such as size and shape stability . Under normal circumstances, the injection molding or extrusion die can be used hot die steel; thermosetting and require high wear resistance, high strength die can be used cold die steel.
