Hassan Sheets and Plates is a reputable manufacturer and supplier of Duplex Steel S31803 Foils based in Riyadh, Saudi Arabia. They specialize in high-quality duplex stainless steel products that are designed for durability, corrosion resistance, and strength. Duplex Steel S31803 is a nitrogen-enhanced duplex grade that merges the advantages of both austenitic and ferritic stainless steels, offering outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking. At Hassan Sheets and Plates, they prioritize precision rolling, a smooth surface finish, and adherence to international standards, making their Duplex Steel S31803 Foils ideal for demanding industries like chemical processing, marine, oil & gas, and power generation.
These foils are made up of 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, with the remainder being iron and trace elements. This unique composition grants them exceptional resistance to chloride-induced corrosion and ensures a well-balanced microstructure with impressive strength. In terms of mechanical properties, S31803 foils boast a tensile strength of around 620 MPa, a yield strength of 450 MPa, and good elongation, providing nearly double the strength of standard stainless steels. They also retain toughness, weldability, and formability even under extreme conditions and high temperatures.
