“…The cause of the strength enhancement is attributed to the solution hardening of the austenite phase due to the partitioning of carbon and nitrogen in the austenite, grain refinement due to the mixed structure, the fiber-strengthening effect of the ferrite phase, and dislocations generated during thermal cycling of the steel. [4] Hence, DSSs are being proposed to replace austenitic stainless steels in industrial applications because of their superior mechanical properties, better corrosion and stress corrosion cracking (SCC) resistance, and cost efficiency as compared to austenitic stainless steel. [5] It is essential to maintain an adequate ferrite/ austenite ratio in DSSs to ensure the good mechanical and corrosion properties of the steel.…”

Duplex stainless steels (DSSs) have generally performed very well in caustic environments. However, some corrosion and stress corrosion cracking (SCC) of DSSs have been reported in different pulp mill environments employing caustic solutions. Studies have shown that the corrosion and SCC susceptibility of DSSs depend on the alloy composition and microstructure of the steel. In this study, the effect of a sulfide-containing caustic environment (pulping liquor) and material properties (DSS alloy composition and microstructure) on the corrosion and SCC of DSSs was evaluated. During metal fabrication processes, localized areas of DSSs may be exposed to different temperatures and cooling rates, which may lead to changes in the microstructure in these regions. This change in microstructure, in turn, may affect the general and localized corrosion or SCC susceptibility of the affected area as compared to the rest of the metal. Hence, the effect of different annealing and aging temperatures as well as cooling rates on the microstructure and corrosion behavior of S32205 DSSs in caustic environment was evaluated. The results showed that changes in the microstructure of S32205 DSSs due to selected heat treatments did not have a significant effect on the general corrosion susceptibility of the steel in caustic environment, but its SCC susceptibility varied with changes in microstructures.

“…Isothermal tests confirmed that deposits of zinc chloride (ZnCl 2 ) or flux on stressed, Type 302 stainless steel pipe surfaces caused SCC after 5200 h (217 days) at 40°C. The pH ranged from 2 to 6 [29]. No cracking was observed on NaClcontaminated pipes.…”

A failure investigation into the root cause of fixed austenitic stainless steel climbing anchor hardware in tropical marine climates has been presented. The incident 316L climbing anchor was fixed in a seaside limestone cliff in southern Thailand and underwent transgranular chloride stress corrosion cracking (TGSCC) after 10 years of service. Since stainless steel does not normally undergo stress corrosion cracking (SCC) at ambient temperatures, the conditions known to promote ambient temperature TGSCC of austenitic stainless steel are reviewed. A mechanism that may give rise to TGSCC in limestone climbing anchors in warm marine environments is postulated.

“…The formation of a passive layer of corrosion inhibitors on surfaces of these materials causes high corrosion resistance [1,2]. Because of their strength, corrosion resistance, mechanical workability, and excellent electrical and thermal conductivities, austenitic stainless steels are one of the most important materials that are used widely in different industries [3][4][5][6]. The corrosion of stainless steel, especially when it occurs in acidic solution, is the concern of the steel users [7].…”

Quantum chemical calculations based on density functional theory method were performed on two pyrimidine derivatives which may be used as corrosion inhibitors for austenitic stainless steel. The quantum chemical properties of the two pyrimidine derivatives that are most relevant to their potential action as corrosion inhibitors have been calculated. To explain the inhibition performance of the pyrimidine derivatives, their local reactivities were analyzed through Fukui functions. The binding energies of the inhibitors with the surface of austenitic stainless steels were studied. A model has been suggested to calculate the approximate inhibition efficiencies of the pyrimidine derivatives. All calculations were carried out in both gas and liquid phases.
