The corrosion behavior of a sputtered micrograin film on Fe-5Cr-5Si alloy in H 2 -CO 2 -H 2 S mixture at 700 °C

Effects of Cr Addition and a Magnetron Sputtered Film on the Oxidation-Sulfidation Behavior of Fe-xCr-5Si Alloys in H2-CO2-H2S Mixture at 800°C

“…In a previous study, we presented a simple model for the formation of the protective layer. 31 The fast initial corrosion of CO Fe-5Cr-5Si transforms into the exceptionally slow corrosion rate at longer times. The formation of the outer FeS layer slows down the inward diffusion rate of sulfur.…”

Effect of Normalizing on Impact and Corrosion Resistance of Low-temperature Service Seamless Steel Pipe

“…When the delayed brittle fracture of metal is caused by the combined action of corrosion and tensile stress in sulfide solution, and the the stress is much less than the yield strength, which is called SSC. It is difficult to monitor and prevent, so hydrogen sulfide corrosion has become a technical problem in the material field worldwide [7][8]. In order to improve the HIC and SSC resistance of low temperature steel pipes, researchers first use the regulation of V, Ti and other microalloy elements to reduce the impact of inclusions, and then use appropriate smelting, rolling and heat treatment processes to optimize the microstructure to refine grains, improve the purity of steel, reduce S and P content, control the number and morphology of non-metallic inclusions [9][10][11], reduce the impact of inclusions, supplemented by appropriate smelting, rolling and heat treatment processes, Finally, the steel pipe with corrosion resistance and low temperature impact performance meeting the standards and operating requirements is obtained.…”
