Forging | 1000-1050 | Cool slowly in calm air or better e.g. in dry ash or other thermally-insulated material | |
Normalization | 790-810 | Cool in air | |
Soft annealing | 750-800 | Warm few hours (according to the size of object), mostly four hours are enough and cool slowly in the furnace | |
Annealing to lower tension | 600-650 | Warm 1 to 2 hours and cool slowly in the furnace | |
Hardening | 1000-1050 | diagram Cool in oil or hot bath, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart | |
Tempering | 150-300 | For cold work | |
400-600 | For hot work |
