![]() Suitable precautions must be taken to prevent excessive carburization or decarburization. They are then held at 1010oC (1850oF) for 20 to 45 minutes and air cooled (air quenched).Īnnealing of D2 tool steels material should be done at 871 to 898oC (1600 to 1650oF) followed by slow furnace cooling at 4.4oC (40oF) per hour or less.after which cooling rate may be increased. AISI D2 steelĪSTM D2 steels alloy should be preheated very slowly to 815oC (1500oF) and then temperature can be increased to 1010oC (1850oF). After D2ĭie steel forging, cool slowly in lime, mica, dry ashes or furnace. Soak through at 1850°-1950☏ and reheat as oftenĪs necessary, stopping work when the temperature drops below 1700☏(926℃). Heating for forging of AISI D2 tool steel shouldīe done slowly and uniformly.
