PROPRIETARY ATI 309S Heat Treatments
- The primary reasons for annealing this alloy is to produce a recrystallized microstructure with a uniform grain size and for dissolving detrimental chromium carbide precipitates. To ensure complete annealing, pieces should be held in the range 1120-1175ºC (2050-2150ºF) for approximately 30 minutes (time at temperature) per inch of section thickness. This is a general recommendation only-specific cases may require further investigation. When properly annealed, this grade is primarily austenitic at room temperature. Some small quantities of ferrite may be present.
