Stress levels may be reduced by annealing or stress relieving heat treatments following deformation, thereby reducing sensitivity to halide stress corrosion cracking. The low carbon Type 304L material is the better choice for service in the stress relieved condition

Jan 02, 2002 · Stress relieving below 400°C is the most common practice, but the result is only moderate stress relief. Stress relieving at temperatures of up to 425 to 925°C will significantly reduce residual stresses which otherwise cause dimensional instability or stress corrosion cracking. One hour of stress relieving at 870°C relieves about 85% of residual stresses.

Relieving stress in stainless steels - ScienceDirect
To avoid these effects, it is recommended that stabilized stainless steel (grade 321 or 347) or an extra-low-carbon type (304L or 316L) be used, particularly when any stress relieving is required. Sensitization in a stainless steel pump component can be seen in Figure 6
Down and Dirty Welding Metallurgy of Stainless Steels
410 stainless will harden by heating and then quenching and needs a stress relieve heat treatment after welding to restore ductility. 410 and other 400 series stainless steels are used for exhaust pipes on automobiles. They can be welded with 309 or 308 rods to avoid the weld hardening.

HEAT TREATMENT OF TOOL STEEL - Uddeholm Global
HEAT TREATMENT OF TOOL STEEL 6 Stress relieving Distortion due to hardening must be taken into account when a tool is rough machined. Rough machining causes thermal and mechanical stresses that will remain embedded in the material. This might not be significant on a symmetrical part of simple design, but can be of great importance in an best stress relieving ss 321

Stress relieving of titanium Stress relieving is probably the most common heat treatment given to tita-nium and titanium alloys. It is used to decrease the undesirable residual stresses that result from nonuniform hot forging deformation, nonuniform cold forming and straightening, asymmetric machining of plate (hogouts) or forgings, welding of
