PROPRIETARY Pyromet Alloy 355 Heat Treatments

Annealing: Heat to 1850/1900°F (1024/1038°C) and cool rapidly Hardening: The alloy can be hardened by either sub-zero cooling or by a double-aging treatment. Hardening by sub-zero cooling will result in higher strength than that attained by double aging. "Conditioning" of the alloy by rapid cooling from 1710/1750°F (932/954°C) is required before either hardening treatment. Double Age: 1350/1400°F (732/760°C) for 3-4 hours, rapid cool; 825/875°F (440/468°C) for 2-3 hours, air cool. The 1350/1400°F (732/760°C) treatment results in carbide precipitation so that the material will completely transfer to martensite when rapidly cooled to room temperature. The treatment at 825/875°F (440/468°C) after transformation provides further increases in strength and hardness. Sub-Zero Cooling: After conditioning, the alloy is held at -100°F (-73°C) for a minimum of 3 hours and then tempered at 850°F (454°C) for the best combination of strength and ductility. If, however, applications require better finish machining characteristics, higher impact strengths, or higher ductilities than are provided by an 850°F (454°C) temper, tempering temperatures up to 1000°F (538°C) may be employed. Optimum stress-corrosion-cracking resistance is provided by the 1000°F (538°C) temper. Equalized and Overtempered: In this variation of double-age, treat at 1375/1475°F (732/801°C) for 3-4 hours, rapid cool, then treat at 1000/1100°F (538/593°C), air cool. This treatment imparts higher ductility and lower hardness than double aging. It is the condition in which this alloy is most readily machined. Bars and billets are normally equalized and overtempered before being "conditioned" for hardening. Surface conditions such as nitriding, carburization, or decarburization are to be avoided as they will inhibit the response of the material to hardening.
