Korean J. Met. Mater. 2023;61(11):830-841.   Published online 2023 Oct 29
DOI: https://doi.org/10.3365/KJMM.2023.61.11.830

Abstract
This study examined the effects of sulfuric acid concentrations on the corrosion behaviors of three types of commercial steels, conventional carbon steel (SA192), sulfuric acid dew resistant steel (S-TEN), and duplex stainless steel (S32205), considered to be potential materials for the heat recovery steam generator (HRSG) in combined cycle power.....

Korean J. Met. Mater. 2022;60(2):114-123.   Published online 2022 Jan 12
DOI: https://doi.org/10.3365/KJMM.2022.60.2.114

Abstract
The study investigated the effect of repeated repair welding on the mechanical properties and pitting corrosion resistance of 25% Cr super duplex stainless steels (UNS S32750). The test coupons were prepared by gas tungsten arc welding (GTAW) with ER2594 filler metal and repaired 3-times at the same weld locations, where..... More
