Abstract

Type 316 austenitic stainless steel submerged arc weld (SAW) deposited metal, produced by joining two heavy (50mm) thickness plates with a multipass procedure and using Type 316L filler metal, was characterized from both a compositional and structural point of view (optical and scanning electron microscopy observation, energy-dispersive X-ray elemental analysis and ferrite content and hardness measurements). Important features such as columnar grain macrostructure, mainly cellular-dendritic and a duplex (γ-austenite matrix plusδ-ferrite second phase) microstructure were observed according to the occurrence of a ferritic-austenitic weldpool solidification mode followed by a solid-stateδγ transformation. The weld deposited metal was characterized along the thickness by significant variations in composition and ferrite morphology, distribution and content because of the influence of the filler metal chemistry and the thermal cycles experienced by each pass during subsequent passes.
