High Carbon, Special Steel

Alloy Steel bar - Die Steel

    Type: round bar, plate

    I.D.: 3-1500mm

    Thickness: 3-180mm

Alloy Steel bar - Die Steel is mainly used for manufacture of cold-work dies with high abrasive resistance 

and small shock load. 

Die steel is a steel used to make molds such as cold die, hot forging die, and die-casting die. Molds are the 

main processing tools for manufacturing parts in industrial 

sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances.
Die steel can be roughly divided into three types: cold-rolled die steel, hot-rolled die steel and plastic die 

steel for forging, stamping, cutting, die-casting and so on. 

Due to the different use of various molds and complicated working conditions, the steel for molds should have 

high hardness, strength, wear resistance, sufficient 

toughness, high hardenability and quenching according to the working conditions of the molds they 

manufacture. Hard and other process performance. Due to the 

different uses and the complicated working conditions, the performance requirements for the steel for the 

mold are also different.
Shanghai Metal Corporation is a professional manufacturer and supplier of  Die steel with high quality and 

reasonable price. If you want to know more about Die
