Material name	Hardness (HRC)	Features	Function	Heat treatment
SKD-11	58~60HRC	High wear-resisting and purity,have good hardenability and machinability.	Widely used in metal stamping mould parts.	200℃
SKH-51(HSS)	Above 63 HRC	Very sharpe,a kind of alloy steel have complicated elements, which included tungsten/molybdenum/chromium/vanadium and cobalt carbide forming elements etc.,	Used in various of cutting tools / cold-punching mould and / embossing die / Punch head etc.,	860~880℃
DC53	62~63HRC	Good hardenability and machinability.	Used in stamping mould/punch head	520~530℃
CK45	55HRC	High quality carbon structural steel, hardness is not high but easy for machining.	widely used as a tip, guide pin, etc., but must have heat treatment.	100℃
42CrMo4	Above 55HRC	High strength, hardenability and good toughness.Easy for polishing, and can have electroplating.	Widely used in plastic injection mould parts.	860℃
Tungten carbide	90-94HRC	Have high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent performance.	Widely used in metal stamping mould parts, such as punch head.	1
