Post-weld heat treatment (PWHT) is applied to steel assemblies primarily to reduce the likelihood of brittle fracture by reducing the level of tensile welding residual stresses and by tempering hard, potentially brittle, microstructural regions. For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels anSee more on twi-global cr to mn to si alloy steel for pressure vesselsIs it necessary to do PWHT on steel assemblies?For large steel assemblies in particular, PWHT can be an expensive operation, and there is thus an economic incentive to avoid PWHT, wherever possible. Whether PWHT is necessary depends on the fracture toughness at the minimum service temperature, the stress levels and the size of any flaws which may be present.See all results for this questionEvaluation of a C Cr Mn Ni Si pressure vessel steel using cr to mn to si alloy steel for pressure vesselsApr 01, 1975 · International Journal of Pressure Vessels and Piping.
