Tanvir Nickel Alloys stands out as a top manufacturer and supplier of Duplex Steel S31803 Pipe Fittings in Cairo, Egypt. They offer high-quality components that are built for strength, durability, and resistance to corrosion. These pipe fittings are meticulously engineered to ensure dependable connections in tough industrial and marine settings. Tanvir Nickel Alloys guarantees that each Duplex Steel S31803 Pipe Fitting adheres to international quality standards, providing consistent performance across the oil & gas, chemical, petrochemical, and desalination sectors, where resistance to corrosion, high pressure, and extreme temperatures is crucial.
Duplex Steel S31803 Pipe Fittings are made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, with the rest being iron and a touch of nitrogen to boost mechanical strength and corrosion resistance. This dual-phase stainless steel boasts a tensile strength ranging from 620 to 850 MPa, along with excellent yield strength and outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. Additionally, these fittings provide good toughness, ductility, and weldability, making them perfect for high-pressure and corrosive environments.
