Cr12 die steel is a typical alloy tool steel. The domestic standard is GB/T 1299-1985.Widely used, it has high strength, better hardenability and good wear resistance, but the impact toughness is poor.It is mainly used for the low impact load, which requires high wear-resisting cold punching die and punch, cold cutting scissors, drill sleeve, gauge, drawing die, embossing die, thread rolling, drawing die and thread rolling mould.

Cr12 belongs to high carbon high chromileite steel, which is also widely used for cold making die steel, which has better hardenability, abrasion resistance and thermal processing.The carbide is well distributed in steel, which can be used to make all kinds of cold mould with complicated shape and heavy working conditions.Such as cold stamping die, thread rolling die, drawing die, material die, metallurgy powder mould, wood cutting tool, cold cutting scissors drill sleeve and gauge, etc.
