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. Are Quenched and Tempered (Q&T) Steels Readily Also denoted by QT or Q/T, these steels are weldable, but care must be taken to adhere to established procedures at all times, as they often have high carbon contents, and thus high hardenability, leading to a hard heat-affected-zone (HAZ) and susceptibility to cracking. The BS EN 10277-5:2008 (old BS 970 Part 3) steels are good examples of these types of steel.

As can be seen from the stress-strain diagram below, a hardened steel has a higher strength value than a quenched and tempered steel (strengthened steel). However, the higher strength has no practical significance, since the hardened steel breaks even at slight deformations.

What is the difference between tempering and stress relief

Jul 05, 2005 · Stress relief is really for the purpose of one of 3 things:1. control distortion immediately following machining, 2. control delayed distortion, and/or 3. reduce premature cracking. Every "good" stress relief process should be able to "consistently" obtain.
