SKH10 High Speed Steel
JIS SKH10 tool steel manufacturers and suppliers,supplied in round rods,flat/square bars,plates,sheets and blocks,produced as hot forged,rolled and cold drawn.
SKH10 steel is a high performance Tungsten-Cobalt tool steel according to JIS Japan standard. SKH10 tool steel is similar to 1.3302 high-speed steel but with added 5% cobalt. The high Vanadium content gives the steel the best cutting performance and durability. The Cobalt content offers high tempering durability and hot hardness.
Carbon:1.45/1.65; Chromium:3.80/4.50; Molybdenum:0.70/1.00; Vanadium:4.20/5.20; Tungsten:11.50/13.50; Cobalt:4.20/5.20;

5.JIS SKH10 HSS Steel Applications
SKH10 steel has proved particularly beneficial in cases where hard materials being processed cause a high degree of wear of the cutting surface, and where the cutting surface is at an elevated temperature. SKH10 tool steel is used in heavy-duty operations,turning knives, milling cutters for rough machining, smoothing,etc.
1)Preheat SKH10 tool steel uniformly and slowly to 860-880°C.
2)Increase the forging temperature up to 1150-1200°C.
3)SKH10 steel should be cooled very slowly after forging.
SKH10 tool steel should be annealed after hot working.Increase the temperature of SKH10 high speed steel to 850°C(Max220°C per hour). Hold at the temperature and then cool slowly with the furnace. The annealed hardness achieved should be below 269HB.
1)Preheat the SKH10 hss steel to 500°C ;
2)Then increase the temperature until 880-900°C;
3)Heating the hardening temperature around 1180°C;
4)SKH10 high speed steel must be heated throughly;
5)Quench in the warm oil,and then complete the quench;
6)SKH10 tool steel is always suitable for vacuum hardening.
1)Temper SKH10 high speed steel immediately after quenching;
2)Heat thoroughly and uniformly to the tempering temperature;
3)Hold for at least two hours (one hour per about 25mm);
4)Triple tempering is strongly recommended for SKH10 tool steel.
