Vipul Sheets and Plates is a reputable manufacturer and supplier located in Delhi, India, specializing in high-quality Duplex Steel S31803 Foil. This foil is perfect for applications that demand exceptional corrosion resistance, strength, and durability. Crafted from UNS S31803 duplex stainless steel, it merges the advantages of both austenitic and ferritic structures, providing outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. Vipul offers S31803 foil in a variety of thicknesses and widths, customized to fit the specific needs of industries like chemical processing, marine, oil & gas, and power generation, all while ensuring consistent quality, precision, and timely delivery.
Duplex Steel S31803 Foil is composed of about 22% Chromium, 5–6.5% Nickel, and 3–3.5% Molybdenum, along with nitrogen and manganese, resulting in a well-balanced microstructure of ferrite and austenite. It boasts high tensile strength (around 620–800 MPa), excellent fatigue resistance, and good weldability. Its corrosion resistance far surpasses that of standard 300 series stainless steels, especially in chloride-rich and acidic environments. This alloy performs admirably at temperatures up to 300°C and retains its mechanical integrity even in harsh chemical conditions.
