SKH2 High Speed Steel
JIS SKH2 high speed tool steel manufacturers and suppliers, supplied in round rods,flat/square bars,plates,sheets,wire and blocks.
SKH2 steel is a typical Tungsten-type high speed tool steel according to JIS standard. It has a high hardness of HRC63~66 after heat treatment. SKH2 tool steel is tungsten series high speed steel which has high hardness and red hardness. Its wide heat treatment quenching is not easy to overheating. The heat treatment process is not easy oxidation decarburization. SKH2 material also has good grinding performance.

5.JIS SKH2 Steel Applications
SKH2 steel is suitable for cutting tools such as twist anchor, broach, tapping, milling wash,reamer.It is also widely used in cold work tools.Such as punching, forming, stamping, and others.
1)Preheat JIS SKH2 high speed steel uniformly and slowly to 850-880°C.
2)Increase the forging temperature to aound 1120°C.
3)SKH2 tool steel should be cooled very slowly after forging.
JIS SKH2 steel should be annealed after hot working. Increase the temperature of SKH2 high speed steel to 850°C at a rate of Max220°C/hour. Hold at this temperature and then cool slowly in furnace. The annealed hardness achieved will be below HB255.
1)Preheat SKH2 hss steel to 480°C ;
2)Increase the temperature up to 880°C;
3)Heating the hardening temperature up to 1200°C;
4)SKH2 high speed steel must be heated throughly;
5)Quench in the warm oil,and then complete the quench;
6)This material steel is suitable for vacuum hardening.
1)Temper SKH2 high-speed steel immediately after quenching;
2)Heat thoroughly and uniformly to the tempering temperature;
3)Hold for at least two hours (25mm one hour);
4)Triple tempering is strongly recommended for SKH2 tool steel.
