Summary: The relationship between microstructure, composition, and localized corrosion resistance of a low carbon CrNi-Mo martensitic-ferritic stainless steel was investigated. The study found that heat treatment significantly influenced the localized corrosion susceptibility. Austenite reversion and other structural transformations decreased the pitting potential.

Summary: A bipolar electrochemistry approach was used to characterize pit nucleation and growth kinetics in 13% Cr ferritic stainless steel. Pits were found to preferentially nucleate and grow with depth to width aspect ratios of 0.4-0.6, and the observed pit growth kinetics were independent of pit volume and the acting potentials.

Summary: A criterion for characterizing the intergranular corrosion sensitivity of 445J2 ultra-pure ferritic stainless steel was established using microstructure analysis and electrochemical impedance spectroscopy (EIS). The differences in the characterization results for the intergranular corrosion sensitivity of 445J2 stainless steel by EIS and the double loop-electrochemical potentiokinetic reactivation test were analyzed. It was determined that the intergranular corrosion in 445J2 is due to the elastic stress field caused by the precipitated phase.

Summary: The effects of alloy elements (Cr, Mn, Cu, Si, Al, Ni, and Ce) on the anti-corrosion behavior and soft magnetic properties of ferritic stainless steel were investigated. The increasing content of Cr, Mn, Cu, and Si improved the anti-corrosion behavior, with Cu being the most effective element. On the other hand, increasing Al and Ce content deteriorated the anti-corrosion performance. Regarding the soft magnetic properties, the addition of Cu, Si, and Ce improved the properties, but their content should be limited. The addition of Cr worsened the soft magnetic properties, while Al proved advantageous. Ni improved the soft magnetic properties, but did not significantly enhance the corrosion resistance and is not necessary due to its cost.

Summary: The effect of annealing temperature on the microstructure, mechanical properties, and anti-corrosion behavior of X2CrNi12 ferritic stainless steel was investigated. Increasing annealing temperature prevents the precipitation of (Fe, Cr)(23)C-6, leading to improved mechanical properties but decreased elongation. The steel annealed at 770 degrees C exhibits the best corrosion resistance.

Summary: This study investigated the corrosion resistance of 7075-T6 aluminum alloy by immersing it in a 3.5% NaCl solution and subsequently repairing the sample surface using ultrasonic nanocrystal surface modification (UNSM). UNSM was found to effectively repair defects and improve stress corrosion crack (SCC) resistance. This improvement was attributed to the compressive residual stress and grain refinement caused by UNSM.

Summary: The advantage of ferritic stainless steels (FSS's) over austenitic stainless steels lies in their lower cost and resistance to chloride attack. This study examines the effect of different fillers on the weldability, microstructure, mechanical properties, and corrosion resistance of 430 ferritic stainless steel. The findings showed variations in phase formation, mechanical properties, and corrosion resistance depending on the filler used, with the 410 filler exhibiting superior qualities in terms of mechanical properties and corrosion resistance.

Summary: Welding has a detrimental effect on the corrosion resistance of both 304 and newly developed steel QN1803. This is mainly attributable to element segregation and decreased pitting corrosion resistance in the fusion zone (FZ) of QN1803 compared to 304.

Summary: Coupon immersion tests on 316L stainless steel in a simulated oilfield environment showed that H2S partial pressure affects pit depth and density, with the most significant pitting observed at intermediate pressures and inhibition of pitting at higher pressures. The pH in the pit solution plays a key role in determining the solubility of metal sulphides and the availability of free H2S for adsorption on the pit surface.

Summary: This study investigates the dependence of the characteristics of nitrided layers on ferritic stainless steel on their initial microstructures. It was found that ferritic stainless steel with a solid solution and annealing treatment showed the best performance after low-temperature plasma nitriding. The nitrided layer thickness and hardness significantly increased, and the wear and corrosion resistance of the nitrided layer were improved.
