Abstract The effect of chemical composition on the behavior of low alloy steels in a hydrogen sulfide environment was studied with regard to corrosion, hydrogen absorption, and sulfide stress cracking. Results were interpreted in connection with microstructure and carbide precipitation. The addition of chromium results in the promotion of hydrogen absorption presumably due to the precipitation of incoherent carbides, thereby reducing, in general, the resistance to SSC. Fine coherent carbides appear to be beneficial, or at least not detrimental, to SSC resistance; e.g., Mo2C, VC, TiC, and NbC. Microstructure seems to affect both hydrogen absorption and SSC resistance largely through the trapping behavior of hydrogen at the carbide/matrix interface.

Abstract Corrosion problems encountered m petroleum refineries processing Western Canadian crude oils, and the methods used to overcome them, are outlined. Hydrogen sulfide and other sulfur compounds, together with hydrochloric acid formed from chlorides in the water associated with the crude oils, are the chief factors in the corrosion of crude distillation units. Preventive measures include desalting, use of alloy materials, neutralization of the hydrochloric acid, and the use of film forming organic inhibitors. Corrosion in catalytic cracking light ends equipment is attributed to nitrogen compounds and cyanides. Water washing to reduce cyanide concentration,, the use of film-forming inhibitors, and the use of corrosion resistant materials are used with success to reduce the severity of the attack. In catalytic reforming units, the problem of high temperature hydrogen sulfide corrosion is overcome by removing the sulfur in a feed preparation unit. Embrittlement of carbon steel by high temperature, high pressure hydrogen is a potential hazard in reforming units, but can be prevented by the use of refractory linings or low alloy steels containing chromium and molybdenum. Under certain conditions, strong acids are formed in these units creating further corrosion problems at temperatures below the dew point. 8.4.3

For fuel savings as well as energy and resource requirement, high strength low alloy steels (HSLA) are of particular interest to automobile industry because of the potential weight reduction which can be achieved by using thinner section of these steels to carry the same load and thus to improve the fuel mileage. Dual phase treatment has been utilized to obtain superior strength and ductility combinations compared to the HSLA of identical composition. Recently, cooling rate following heat treatment was found to be important to the tensile properties of the dual phase steels. In this paper, we report the results of the investigation of cooling rate on the microstructures and mechanical properties of several vanadium HSLA steels.The steels with composition (in weight percent) listed below were supplied by China Steel Corporation: 1. low V steel (0.11C, 0.65Si, 1.63Mn, 0.015P, 0.008S, 0.084Aℓ, 0.004V), 2. 0.059V steel (0.13C, 0.62S1, 1.59Mn, 0.012P, 0.008S, 0.065Aℓ, 0.059V), 3. 0.10V steel (0.11C, 0.58Si, 1.58Mn, 0.017P, 0.008S, 0.068Aℓ, 0.10V).
