PROPRIETARY Pyromet Alloy 350 Heat Treatments

Annealing: Heat to 1010/1066°C, cool rapidly to room temperature. Hardening: hardened by either sub-zero cooling and tempering (SCT) or double aging (DA). Sub-zero cooling and tempering will result in higher strength than double aging. "Conditioning" of the alloy by rapid cooling from 1710°F (932°C) ±25°F is required before the SCT treatment, and is not required but is recommended before double aging. It is further recommended that following an anneal at 1850/1950°F (1010/1066°C), Pyromet alloy 350 be cooled to -100°F (-73°C) for at least 3 hours before hardening. Double Age: Hold for 3 hours at 1350/1400°F (732/760°C), air cool to room temperature; heat to 825/875°F (440/468°C), hold 2-3 hours, air cool. Sub-Zero Cooling: r conditioning at 1710°F (932°C) ±25°F (rapid cool) for 90 minutes per inch (25.4 mm) of thickness, Pyromet alloy 350 is held for a minimum of 3 hours at -100°F (-73°C), then tempered at either 850°F or 1000°F (454°C or 538°C) for a minimum of 3 hours. The 850°F (454°C) temper produces the highest strengths and hardnesses, and the 1000°F (538°C) temper produces improved toughness and stress corrosion properties. Equalized and Overtempered: Bars and billets are normally shipped in this condition unless otherwise specified. This treatment, 1375/1475°F (745/801°C), 3-4 hours, air cool to room temperature, then 1000/1100°F (538/593°C), 3 hours, air cool, produces a stable tempered martensitic structure which is most readily machinable.
