Heat treatment of steel W. Nr. 1.2085
|Forging||800-1100||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||850-880||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||Cool in oil or hot bath, the degree of tempering is set by hardness and toughness of instrument according to the tempering chart|
