PROPRIETARY WM SCK Tratamiento Térmico
- Forging:Heating for forging must be done slowly and uniformly. Soak through at 1900-2000°F (1038-1093°C), and reheat as often as necessary, stopping work when the temperature drops below 1700°F (927°C). After forging cool slowly in lime, mica, dry ashes, or furnace. Should always be annealed after forging.
Annealing:Heat slowly to 1600-1650°F (871-899°C), hold until the entire mass is heated through, and cool slowly in the furnace (25°F (14°C) per hour) to about 1000°F (538°C), after which the cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Strain relieving:When desirable to relieve the strains of machining, heat slowly to 1050-1250°F (566-677°C), allow to equalize, and then cool in still air.
Preheat for hardening:Warm slightly before charging into preheat furnace, which should be operating at 1400-1500°F (760-816°C).
Hardening:After through preheating, transfer to the hardening furnace, operating at 1900-2050°F (1038-1121°C), depending upon the degree of hardening required for the applications, and the size of the tool.
Quenching:It is an air hardening steel, and will develop full hardness on cooling in still air. If the scaled surface resulting from air cooling is objectionable, the part may be quenched in oil until it has lost its color (1000-1200°F (538-649°C)), and then allowed to cool in still air. Parts should be allowed to cool to 150°F (66°C), or to where they can be held in the bare hand, and then tempered immediately.
Tempering:For the optimum combination of hardness and mechanical properties, it is recommended to be tempered at or beyond its maximum secondary hardness, or in the range of 900-1000°F (482-538°C). Double tempering is recommended.
