    Dr. Janardhan Saithala, coauthor of the paper entitled “Environmental Assisted Cracking Behavior of Sigmatized Super Duplex Stainless Steel” is recognized for his outstanding manuscript as a young author.

    Super duplex stainless steel is widely used in the oil and gas industry for process equipment such as pipes, fittings, tubes, top-side pipework, flow lines, seawater handling systems, and subsea umbilicals. Compared to traditional austenitic stainless steel, super duplex stainless steel exhibits better mechanical and corrosion properties. However, if these are incorrectly heat treated, they may suffer from intermetallic-phase precipitation (such as sigma phase), which will degrade their mechanical and corrosion-resistant properties. Deviation in quality of the steel can result in serious downtime for oil and gas production operations. This paper studies the effects of sigma phase stress corrosion cracking behavior specific to super duplex stainless steel in aggressive environments. There have only been a limited number of studies examining sigma phase and stress corrosion cracking behavior in aggressive environments, and prior to this paper, none relating specifically to simulated oilfield environments.
