Aisha Nickel Alloys is a trusted manufacturer and supplier of Super Duplex Steel Flanges S32750 in Muscat, Oman. We provide high-performance flanges engineered for applications demanding exceptional corrosion resistance and mechanical strength. Our S32750 flanges are manufactured to international standards and undergo rigorous quality inspections to ensure dimensional accuracy, mechanical integrity, and long service life. Serving industries such as oil & gas, chemical processing, petrochemical, desalination, and marine, we focus on delivering flange solutions that engineers can rely on, backed by technical expertise and responsive customer service.
Super Duplex Steel S32750 flanges are made from a high-alloy duplex stainless steel containing approximately 25–26% chromium, 6–7% nickel, 3–5% molybdenum, and nitrogen. This composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. The alloy offers high tensile and yield strength, excellent toughness, and good ductility. S32750 flanges maintain mechanical stability across a wide temperature range and perform reliably in harsh chemical, seawater, and high-pressure environments.
