Forging:

• HForging of D2 steels can be done from 1065ºC (1950ºF) down to 954ºC (1750ºF). Do not forge below 926ºC (1700ºF).

Annealing:

• D2 is supplied in the annealed and machineable condition. Re-annealing will only be necessary if the steel has been forged or hardened by the toolmaker. To anneal, heat slowly and uniformly to 900°C. Soak for three to four hours and allow to cool in the furnace to room temperature. Re-heat to 800-1040°C and again soak for three to four hours. Allow to cool in the furnace to room temperature.

Hardening:

• It is preferable to heat the tools in a controlled atmosphere. If this is not possible, pack hardening is recommended. A reducing atmosphere is desirable. Pre heat the D2 tool steel component to 750-800°C. and allow to soak at this temperature. The tools may then be brought up to 1000-1040°C for air cooling, or 980°C for oil quenching. Soak thoroughly at the temperature for thirty minutes per 25mm of ruling section, then cool or quench accordingly. It is important not to exceed 1020°C when heating for hardening.

Heat Treatment:

• Carbonisation of EN1A bright mild steel takes place at 900-950°C (1652°F- 1742°F) then it is furnace or air cooled.
• En1A can be tempered at 180-210 °C (356 °F- 410°F) then should be left to cool in air.
• The mild steel can be hardened at 780-800°C (1436°F- 1472°F) then quenched in oil or water. However this is difficult to do with EN1A and is not recommended.

Mechanical Properties:

Physical Properties(avarage values) at ambient temperature:

Application:

• The low carbon steels, such as C15 are used for applications such as cold headed fasteners and bolts.
