Characteristics of the material: The code name of steel is medium carbon ultra-high strength steel and new hot work die steel. It is a new die-casting die steel that can replace 3 steels. Its chemical composition is similar to that of 3 steel, and it has good hardenability. Molybdenum and vanadium alloy elements play a great role in refining the grains, improving heat permeability and tempering resistance. This steel is an air-cooled hardening hot work die steel. It is a type of steel developed by my country on the basis of BR steel. The steel does not contain cobalt and has an increased mass fraction of approximately chromium, silicon, manganese and molybdenum. The content is slightly higher, the vanadium content is slightly lower, the chemical composition is similar to steel, its melting, forging, workability is good, and the hardenability is high.
The steel has good mechanical processing properties and hot processing properties, and has good thermal fatigue resistance. Compared with 3 steel, this steel also has the advantages of small heat treatment deformation and good resistance to aluminum dissolution. The service life of the mold is generally more than double that of molds made of 3 steel. It is recommended that the steel be used when quenched and tempered to a hardness ~.
