Duplex Steel S31803 Pipe Fittings Manufacturer

Overview of Duplex S31803 Pipe Fittings
Duplex S31803 is a type of alloy that features a ferritic-austenitic microstructure. In its annealed state, the alloy comprises ferrite. The duplex grade is renowned for its high strength, similar to ferritic grades, and corrosion resistance, similar to austenitic steel. Due to its austenite and ferrite phases, the alloy exhibits properties characteristic of both types of steel.

Composition of Duplex S31803 Pipe Fittings
The fittings comprise Nickel, Iron, Copper, Chromium, Silicon, Manganese, and Nickel alloys. These alloys have excellent weldability and low-temperature toughness, making them ideal for this application.

Properties of Duplex S31803 Pipe Fittings
Duplex S31803 pipe fittings are highly resistant to stress chloride corrosion cracking. They perform exceptionally well in sulfide environments and at high temperatures, up to 300°C, where increased chloride offers protection against corrosion. The fittings also exhibit better flexibility at low temperatures than ferrite grade. They provide superior resistance to chloride pitting and crevice corrosion and outstanding corrosion resistance to seawater and most concentrations of sulphuric acid. Additionally, they are resistant to sulfide stress corrosion cracking and sour-gas environments.

Applications of Duplex S31803 Pipe Fittings
Duplex S31803 pipe fittings, including Duplex Steel S32205 instrumentation valves, are highly versatile and widely used in various applications. They are commonly employed in seawater systems, pumps, valves, chemical process vessels, piping, heat exchangers, and FGD scrubber systems. Additionally Duplex Steel S31803 Instrumentation valves used in pulp mill digesters, bleach washers, food process equipment, and oil field piping, among others.
