EFFECTIVENESS OF VARIOUS TEMPERATURES FOR STRESS RELIEVING WELDED TYPE 347 STAINLESS STEEL
Technical Report
·
OSTI ID:4355875
Welded-up ring samples of Type 347 stainless steel were given a number of different thermal treatments to study their effectiveness of relieving locked- up stresses. Temperatures of 1650 and 1850 deg F caused complete relaxation. At lower temperatures of 1100 and 1200 deg F the amount of relaxation obtainable over reasonable periods depended upon the magnitude of the residual stresses. Experiments conducted on twisted Type 347 wire showed that relaxation occurs at low temperaiures. A treatment of 1100 deg F produces some untwisting and establishes a pattern of residual stresses which does not cause any further movement when the wire is cycled from room temperature to 850 deg F.
