Abstract: Stress corrosion cracking (SCC) of UNS S31603 austenitic stainless steel (ASS), UNS S32205 duplex stainless steel (DSS) and UNS S32750 super duplex stainless steel (SDSS) was investigated. SCC tests were carried out at 110 ºC for 500 h under drops of synthetic seawater (DET, drop evaporation test). Two loading conditions were investigated: 50 % and 100 % of the experimental yield strength of each steel. DSS and SDSS specimens showed no susceptibility to SCC under loading of 50 % of their yield strength, contra… Show more

“…Thus, SCC crack growth occurs under the combined effect of a chemical reaction plus local tensile stresses that are above some threshold value but below the level required for fast crack propagation. 44,45 SCC has led to catastrophic results, such as the collapse of the Silver Bridge across the Ohio River. In that case, local rusting led to stress corrosion cracks that followed grain boundaries in the steel.…”

“…Wan et al evaluated the welded joints of X65 steel exposed in the shallow deep sea [3]. It is found that the high hydrostatic pressure, low hydrogen, and temperature trigger localized corrosion induced SCC [4,5]. Various efforts have been conducted to understand and mitigate the SCC in stainless steels and their welding joints; however, these studies mostly focus on the welding joints of similar metals while the real challenge in dissimilar metal welds is still overlooked [6][7][8].…”

“…The polished samples were electrolytically etched in 10% oxalic acid or potassium hydroxide (KOH) solutions. For both etchings, a voltage of 10 V was applied for 30 s, as previously described 11,19,20,28 . The metallographic examinations were performed in the three regions of the weld beads: molten zone (MZ), bound zone (BZ) and heat-affected zone (HAZ) of the welded joints as described in Figure 1.…”

“…They explained this result by the secondary austenite precipitation and the formation of intermetallic phases during the thermal cycling of the welds with higher heat inputs. Recent studies 19,20,21 performed on UNS S32205 duplex stainless steel have shown that the nucleation of SCC (stress corrosion cracking) may occur in corrosion pits 28 . At temperatures between 70 ºC and 110 ºC in a synthetic seawater-dropping-solution environment, the preferential corrosion of the ferrite has been observed 19,20 .…”
