PROPRIETARY Trinamet Heat Treatments

Annealing: Heat uniformly to 732–788°C (1350–1450°F) for two to four hours on heat, remove from furnace and cool to room temperature. The hardness will be approximately Rockwell B 95 or equivalent. For lowest hardness, Rockwell B 88–93, heat to 880°C (1615°F) for one to two hours on heat, cool in the furnace at a rate not exceeding 28°C (50°F) per hour to 650°C (1200°F), and then remove from the furnace and air cool to room temperature.
Hardening: Trinamet stainless readily lends itself to heat treating in both batch and continuous types of heat treating furnaces. For the maximum attainable hardness of Rockwell C 49–52, the alloy should be heated to 1040–1065°C (1900–1950°F) and rapidly cooled to room temperature by quenching in oil or by forced air or gas cooling. Fifteen minutes on heat at 1040–1065°C (1900–1950°F) is generally adequate for screws, clips, pins, wire, and other small parts. A longer time (up to a maximum of about one hour) is required for larger sections. When heat treating in a protective atmosphere, nitrogen or argon with a dew point no higher than –40°C (–40°F) is suggested. Dissociated ammonia is considered unsuitable because of the risk of nitriding the work and the resulting reduction in corrosion resistance.
Tempering: After hardening, parts should be tempered for one to two hours at 177–204°C (350–400°F). When less than maximum hardness is required, parts may be tempered up to 316°C (600°F).
