This paper describes the creep of Type 304 stainless steel plate weldments as influenced by the level of ferrite and the geometries of the Type 308 stainless steel weld metal. The method of testing enabled multiple determinations of the strains for weld metal, heat-affected zone (HAZ), and base metal at crack initiation and rupture. The tests of weldments included two levels of ferrite, 2 FN and 9 FN, and two weld geometries-75 deg V-groove weld and a single, square groove weld made from one side with a backing plate at the weld root. All tests were performed at 24 ksi (165 MPa) and 1100/sup 0/F (593/sup 0/C). The weldments with a central axial weld and constraints at the ends of the gage section were tensile loaded. Therefore, all zones of the weld are subjected to the same overall axial deformation. This loading and constraint is similar to a circumferential weld in a pipe or vessel. The failure mode was a function at all three of the following: The relative strengths and ductilities of the weld metal, heat-affected zone (HAZ) and the base metal. The residual stresses and deformations from the welding process. The stress and strain histories under loading.
