Nasir Nickel Alloys in Manama, Bahrain, supplies Super Duplex Steel Coil S32750, a highly alloyed stainless steel designed for exceptional corrosion resistance and mechanical strength. With approximately 24-26% chromium, 6-8% nickel, 3-5% molybdenum, and nitrogen content of 0.24-0.32%, this duplex stainless steel achieves a balanced microstructure of ferrite and austenite, providing superior resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments. The coil form offers high tensile strength between 730-930 MPa and yield strength above 530 MPa with elongation of 25%, making it suitable for harsh applications like offshore platforms, chemical processing, and desalination plants.
Super Duplex Steel S32750 coils come in various thicknesses from 0.5 mm up to 12 mm and widths up to 2000 mm, enabling versatile fabrication into sheets, strips, and shims. These coils meet ASTM A240 and ASME SA240 standards, ensuring consistent quality for industrial uses. Their excellent corrosion and erosion resistance combined with high strength and impact toughness make them reliable in oil and gas, petrochemical, marine, and power generation applications where durability against aggressive media and mechanical stresses is crucial.
