Duplex Steel S31803 Flanges

The chemical composition includes chromium, molybdenum, nickel, sulfide, nitrogen, and silicon, with traces of iron and carbon present. Duplex Steel Flanges S31803 is ideal for applications that often require weld maintenance or replacement as this flange has high weldability characteristics. This steel is used for both applications that require extreme strength and elevated temperatures or low-temperature environments where low thermal expansion properties are necessary.

Duplex Steel S31803 Flanges are highly useful in various situations, as they possess features that make them advantageous over other steel flanges. Their strength and corrosion resistance are nearly double that of standard austenitic stainless steel, making them ideal for applications operating with high temperatures and pressures. This duplex steel material has the added benefit of excellent pitting, crevice, and stress-corrosion cracking resistance. Furthermore,  S31803 Duplex Steel Flanges have excellent weldability comparable to ferritic stainless steels. Because of their unique mechanical and physical properties, Duplex Steel S31803 Flanges are often used for demanding applications with high performance. Without issues, they can be used in industries such as oil & gas extraction, marine environments, offshore platforms, and chemical processing plants.
