“…The tendency of dendritic boundaries to melt in alloy AISI 304 is attributed to the enrichment of niobium in these boundaries. As reported by Naffakh et al, 8) Niobium not only lowers the melting point constitutionally, but also forms low-melting carbide-austenite eutectics during solidification.…”

“…12) It was reported by Naffakh et al 8) that higher amounts of nickel and lower amounts of chromium can dissolve the Nb in Inconel A austenite matrix to a superior extent and as a result the formation of low melting phases in the inter-granular region decreases. The results reported by the authors were in agreement to this work such that the weld interface of AISI 304 side was found to have the formation of secondary phases where the amounts of Ni and Cr was almost equivalent (EDAX analysis).…”

“…The presence of 3% Nb stabilizes the austenitic matrix. Naffakh et al 8) employed gas tungsten arc welding (GTA) for joining Inconel 657 and AISI 310 using nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and 310 austenitic stainless steels. Authors reported that the presence of iron in nickel based superalloys lowers the niobium solubility in austenite phase and the presence of Niobium not only lowers the melting point constitutionally, but also forms low-melting carbideaustenite eutectics during solidification.…”

This investigation has been performed to characterize the microstructure and mechanical properties of the GTA and PCGTA welded dissimilar combinations of Inconel 625 superalloy and AISI 304 austenitic stainless steel. These welds were obtained by employing ERNiCrMo-3 filler metal. The weldments were characterized by the combined techniques of optical microscopy and SEM/EDAX analysis. Hardness and tensile studies were conducted to assess the mechanical properties of the weldments. Tensile studies showed that the fracture had occurred at the parent metal of AISI 304 side in both the cases.KEY WORDS: gas tungsten arc welding; pulsed current gas tungsten arc welding; alloy 625; austenitic stainless steel AISI 304; filler metal.

“…DSS, which possess good strength, high toughness and excellent resistance to SCC and localized corrosion (pitting) are more recommended in applications where the maximum working temperatures are approximately 350 • C. As a result, the necessity of joining DSS and austenitic 310S stainless steel is indispensable [3,8].…”

Abstract:The influence of the weld metal chemistry on the stress corrosion cracking (SCC) susceptibility of dissimilar weldments between 310S austenitic stainless steel and 2304 duplex steels was investigated by constant load tests and microstructural examination. Two filler metals (E309L and E2209) were used to produce fusion zones of different chemical compositions. The SCC results showed that the heat affected zone (HAZ) on the 2304 base metal side of the weldments was the most susceptible region to SCC for both filler metals tested. The SCC results also showed that the weldments with 2209 duplex steel filler metal presented the best SCC resistance when compared to the weldments with E309L filler metal. The lower SCC resistance of the dissimilar joint with 309L austenitic steel filler metal may be attributed to (1) the presence of brittle chi/sigma phase in the HAZ on the 2304 base metal, which produced SC cracks in this region and (2) the presence of a semi-continuous delta-ferrite network in the fusion zone which favored the nucleation and propagation of SC cracks from the fusion zone to HAZ of the 2304 stainless steel. Thus, the SC cracks from the fusion zone associated with the SC cracks of 2304 HAZ decreased considerably the time-of-fracture on this region, where the fracture occurred. Although the dissimilar weldment with E2209 filler metal also presented SC cracks in the HAZ on the 2304 side, it did not present the delta ferrite network in the fusion zone due to its chemical composition. Fractography analyses showed that the mixed fracture mode was predominant for both filler metals used.

“…Recently, these welding processes has been applied to weld the dissimilar metals and showed the experimental results that could be applied effectively in the industries. These consisted of the welding of martensitic stainless steel to austenitic stainless steel [4], the welding of duplex stainless steel to carbon steel [5], the welding of austenitic stainless steel to inconel [6], the welding of austenitic stainless steel to titanium [7]. These studies have been done for optimization of the electrode for welding the dissimilar metals joint consisting of the stainless steel.…”
