About postweld heat treatment/stress relief heat treatment

Post Weld Heat Treatment (PWHT),or stress relief as it is sometimes known,is a method for reducing and redistributing the residual stresses in the material that have been introduced by welding..The extent of relaxation of the residual stresses depends on the material type and composition,the temperature of PWHT and the soaking time at that temperature.ASM Heat Treating Aluminum for Aerospace Applicationsquench tank,with each tank containing a different quenchant.A typical solution heat-treating furnace and quench tank used for heat-treating aluminum aerospace components is shown in Figure 4.Fink and Wiley Figure 4 - Large drop-bottom furnace used to solution heat- treat and quench aluminum alloys.Quenching.An understanding of heterogeneous results for this questionWhat is the stress relief temperature of stainless steel?What is the stress relief temperature of stainless steel?In another example4,stress relief yields maximum me- chanical properties in 302 stainless steel wire between 600 larger diameter tanks Stress relief heat treatment#176;F (315 larger diameter tanks Stress relief heat treatment#176;C) and 900 larger diameter tanks Stress relief heat treatment#176;F (480 larger diameter tanks Stress relief heat treatment#176;C).The fatigue properties of the wire are optimum at a stress relief temperature of 1200 larger diameter tanks Stress relief heat treatment#176;F (650 larger diameter tanks Stress relief heat treatment#176;C).Stress Relief - Heat Treat Doctor
