ASME SA-249 TP 348 Heat Treatments

  • Solution heat treated at min 1040°C (1900°F). A solution treating temperature above 1065°C (1950°F) may impair resistance to intergranular corrosion after subsequent exposure to sensitizing conditions. When specified by the purchaser, a lower temperature stabilization or re-solution anneal shall be used subsequent to the higher-temperature solution anneal prescribed. Quenched in water or rapidly cooled by other methods. When stress-relieved tubes are specified, tubes shall be given a heat treatment at 845-900°C (1550-1650°F) after roll straightening. Cooling from this temperature range may be either in air or by slow cooling. No mechanical straightening is permitted after the stress-relief treatment.
