ASME SA-557 Grade A2 Heat Treatments
- Following welding, tubes shall be normalized at a temperature of at least 860°C (1600°F) followed by cooling in air or cooling in the cooling zone of continuous atmosphere controlled furnace.
If cold drawn, tubes shall be heated after the final cold-working operation to a temperature of at least 640°C (1200°F) to ensure ductility satisfactory for rolling into tube sheets and to meet the specified mechanical properties.
If heat treatment of the U-bends is specified, such heat treatment shall consist of heating the stressed portion within a range from 590 to 640°C (1100 to 1200°F).
