Forging of HSS T15 Tool steel-ASTM A681
Slowly Heat to 816-871 °C, Then rapid heating to 1180°C.keep the temperature to heat thoroughly. Start forging. Finished cool slowly. Below 980 °C no forging process.
Annealing of SAE AISI T15 tool steel material
Heat to 870-900°C, soak enough time, and ensure heat thoroughly. Then cool in the heat treatment furnace. After Annealing get Hardness 277 HRc Max.
Quenching of SAE T15 material
Preheat temperature /°C: 816 ~ 816
Quenching temperature /°C| salt bath furnace: 1200
