PROPRIETARY RA330 Heat Treatments

Fully austenitic alloy which does not harden by thermal treatment. Increased room temperature strength may be obtained only by cold working. The purposes of annealing are to remove residual forming stresses or to redissolve precipitated carbides. For most high temperature applications, RA330 fabrications are not annealed after forming or welding.
If the final application requires a full anneal, the suggested procedure is to heat in a low-sulfur atmosphere 1066-1121°C (1950-2050°F) long enough to ensure a uniform actual metal temperature, followed by a rapid air cooling or quenching to below 427°C (800°F). Residual stresses and work hardening from severe forming operations may be removed by an 1010-1038°C (1850=1900°F) anneal.
