Forging of HSS T1 Tool steel-ASTM A681

Slowly Heat to 816-871 °C, Then rapid heating to 1093°C.keep the temperature to heat thoroughly. Start forging. Finished cool slowly. Below 932 °C no forging process.

Annealing of SAE AISI T1 tool steel material

Heat to 850 °C, soak enough time, and ensure heat thoroughly. Then cool in the heat treatment furnace.

Quenching of SAE T1 material
