SK2 Carbon tool steel 


 SK2 Japan Carbon tool steel, the steel has high strength, good wear resistance, sufficient toughness and good durability, with good machinability characteristics. For the manufacture of simple shapes of small tooling. 



 SK2 high carbon tool steel 
 Japan JIS G4401 supplier performance standards hardness of soft state, semi-hard, hard state (thermal material) cold white surface color, blue, golden, color SK2 chemical heat treatment of carbon (C) 1.10 ~ 1.30 manganese (Mn) ≤ 0.50 Si (Si) ≤ 0.35 phosphorus (P) ≤ 0.030 Sulfur (S) ≤ 0.030 

 Characterization of the carbon steel part of the Japanese tool steel, high strength, wear resistance, sufficient toughness and durability, machinability is good, no deformation of the poor quenching, tempering poor stability. Starting temperature of thermal processing specification 1000 ~ 1050 ℃. Quench hardening temperature Specification 750 ~ 780 ℃, hardening, tempering hardness 63HRC. Application examples for the shape of a simple small tool and die.
