ASME SB-658 Grade R60705 Heat Treatments


  • Welds shall be stress relief annealed within 14 days after welding to prevent delayed hydride cracking. The heat treatment shall be as follows: the stress-relieving treatment shall consist of holding the pipe at a minimum temperature of 600°C [1100°F] for not less than 30 min per 25,4 mm of the maximum thickness in a nonreducing atmosphere. The minimum time at this temperature is 15 min.
