Duplex steel stands out in manufacturing circles due to its exceptional robustness, endurance, and resistance to corrosion. Among the most prevalent variants are S31803 and S32205. These alloys find extensive utility across diverse sectors such as chemical processing, oil exploration, marine construction, and infrastructure development. S31803 Duplex Steel boasts a dual-phase microstructure comprising austenitic and ferritic phases, delivering superior protection against corrosion and chloride stress cracking compared to its stainless steel counterparts.
