Duplex Steel S31803 Pipe Fittings

S31803 Duplex steel pipe fittings rely upon a chemical composition combining elements of austenite and ferrite steel sheets. This particular composition involves high amounts of chromium and nickel, approximately 22 to 24 per cent chromium and 5 to 6 per cent nickel, as well as other small amounts of other elements such as molybdenum and copper. The result is a combination of corrosion resistance with excellent strength at elevated and cryogenic temperatures up to three hundred thirty-five degrees Fahrenheit while also providing good mechanical properties. Although it has a lower yield strength than the standard duplex stainless steel, it offers other unique benefits compared to standard austenitic stainless steel.

Duplex steel S31803 pipe fittings are highly reliable and cost-effective components used in industrial projects. These fittings offer strength, toughness, hardenability, and excellent resistance to seawater erosion and crevice corrosion while providing outstanding weldability and formability. This high-quality alloy is highly versatile, which makes it ideal for essential engineering applications such as structural components and tubing. UNS S31803 pipe fittings contain more significant amounts of chromium and molybdenum. They can be utilized to ensure maximum service life even in the harshest conditions making them a preferred choice amongst businesses operating in heavily corrosive environments. Additionally, this strong alloy is well suited to creating complex shapes with precise detail, reducing fabrication costs when producing fittings.
