ASME SA-234 Grade WPR Heat Treatments
- Fittings, after forming at an elevated temperature, shall be cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air.
Hot-formed fittings upon which the final forming operation is completed at a temperature above 620°C (1150°F) and below 980°C (1800°F) need not be heat treated provided they are cooled in still air.
Hot-formed or forged fittings finished at temperature in excess of 980°C (1800°F) shall subsequently be annealed, normalized, or normalized and tempered.
Cold-formed fittings, upon which the final forming operation is completed at a temperature below 620°C (1150°F), shall be normalized, or shall be stress relieved at 595 to 690°C (1100 to 1275°F).
Minimum tempering temperature shall be 595°C (1100°F).
Liquid quenching followed by tempering shall be permitted when approved by the purchaser.
