PROPRIETARY CarTech M10 High Speed Steel Heat Treatments

  • Decarburization: This steel is somewhat susceptible to decarburization in hardening, means of preventing this are well known. If proper control of atmosphere is maintained, this steel will present no difficulty with decarburization.
    Normalizing: Normalizing is not recommended.
    Annealing: Pack in a suitable container with clean cast iron borings, heat uniformly to 843-871°C (1550-1600°F) and cool slowly in the furnace to 649°C (1200°F) at a rate of 11-22°C (20-40°F) per hour. To relieve machining stresses for greater accuracy in hardening - first, rough machine, then anneal in the temperature range of 677-704°C (1250-1300°F) and cool slowly - then finish machine.
    Hardening: This steel should be heat treated from neutral salt baths or properly adjusted controlled atmosphere furnaces. A dew point of -12°C (+10°F) is suggested for the high heat furnace when using controlled atmosphere. First, preheat to 760-816°C (1400-1500°F), then transfer to a superheating furnace with a temperature maintained at 1177-1218°C (2150-2225°F). When neutral salt baths are used for hardening, the temperature should be dropped 14°C (25°F) as compared to other furnace temperatures. Exercising the usual control of temperature and atmosphere, there should be no difficulty with decarburization. Quench in oil - and be sure that tools are cooled below 93°C (200°F) before tempering (cool enough to hold in your hand). Small sizes under about 25.4 mm in diameter or delicate sections may be hardened by cooling in still air. It is also acceptable to quench in molten salt at about 538-593°C (1000-1100°F), equalizing for about 5 minutes per inch followed by air cooling.
    Tempering: Be sure to allow sufficient time for the tool to reach the proper temperature and then start timing the tempering operation. Tools should be tempered immediately after the completion of the quench. For best results with most tools, a range of 538-649°C (1000-1200°F) is suggested. For cutting tools, double or triple temper at 538-566°C (1000-1050°F) where maximum wear resistance is desired.
