Forged of 1.2083

Pre-Heating to 600℃，Then heat to forged temperature. Soak at 800-1100°C, ensure heat thorough. Then start forged, the forged temperature no low than 650℃. After forging, cool slowly.

Heat Treatment of DIN 1.2083 Plastic Steel

1.2083 Annealing

Slowly heat to 750-800℃，then slowly Cools to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 225 Max

Din W-Nr 1.2083 Hardening

1.2083 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested.
