Hassan Sheets and Plate, based in Riyadh, Saudi Arabia, has built a solid reputation as a reliable manufacturer and supplier of top-notch metal products for a variety of industrial sectors. One of their standout offerings is the **Duplex Steel S31803 Coil/Slitting Coil**, which is celebrated for its remarkable mechanical strength and outstanding resistance to corrosion and stress cracking. These coils are specifically designed to perform well in tough, high-stress environments, making them perfect for fabrication, forming, and structural applications. With a commitment to precision manufacturing and strict adherence to international standards, Hassan Sheets and Plate delivers durable and dependable coil products for industries like oil & gas, chemical processing, and marine infrastructure.
The **Duplex Steel S31803 Coil/Slitting Coil** is made up of about 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen. This unique alloy boasts a dual-phase microstructure of austenite and ferrite, giving it nearly double the strength of regular stainless steels. It features high tensile strength (around 620 MPa) and excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, along with good weldability and toughness, even in low temperatures.

Duplex steel S31803 coil/slitting coils offer a unique combination of advantages, including high strength and good corrosion resistance, especially against pitting, crack corrosion and stress corrosion cracking Their dual phase design ensures good mechanical properties, e.g higher tensile and yield strengths compared to austenitic steels reduce them in good weldability and formability, and provide they are suitable for complex applications. Furthermore, their high fatigue and corrosion resistance makes them durable in harsh environments, such as chemical manufacturing, marine, and oil and gas industries, and allows them to use time long and reliable.
