Application of JIS High Speed Tool Steel SKH52 material Grade number

Because of high speed tool steel SKH52 is grinding performance is good, so can be used to manufacture all kinds of complex high precision cutting tool.

Typical Application like Scraper, rolling cutter, iron knives, drill bits, etc

Forging of Tool Steel HSS JIS SKH52

982-1093°C,  heat thoroughly, then start forging. slowly cool in furnace.

Annealling of SKH52 Steel JIS HSS tool material

Heat to 871°C, soak thoroughly. then cool slowly in heat treatment furnace

Stress Relieving of JIS SKH52 High Speed Tool Steel

Heat slowly the SKH52 Steel component to 600-650°C and soak well (about two hours) , Then Cool slowly in the furnace.

Tempering of High Speed Tool Steel JIS SKH52 steel grade

Tempered SKH52 Tool Steel for three times at 515-593°C, then cool slowly at furnace.  Typical Tempering as below table:

Temperature [°C]   515    550     600
