Duplex steel UNS 31803 Flanges are incredibly versatile. They can be used in various settings across industries, such as petrochemical refineries, power plants, water treatment facilities, food processing plants, and more. They are also commonly used in piping systems where high temperatures and pressures are expected due to their superior strength to other materials such as stainless steel or carbon steel. They offer excellent corrosion resistance, ideal for corrosive environments like seawater piping systems. Furthermore, they can also be used in non-corrosive environments due to their low maintenance requirements. In addition to our range of Duplex Steel UNS S31803 Flanges we also offer a variety of Cupro Nickel 70/30 Flanges to meet your piping needs.

At Metcore Steel, we pride ourselves on providing excellent customer service and offering a wide range of products, including Duplex Steel UNS S31803 Flanges and Incoloy 800 Flanges.

Their superior strength, combined with their flexibility in applications, makes them highly sought after by businesses looking for reliable solutions that require minimal maintenance while still being able to withstand extreme temperatures and pressures.

Duplex Steel UNS S32205 Flanges come in five different types. Slip-on flanges have an inside diameter slightly larger than the pipe connected to it and can be easily installed by slipping it over the end of the pipe. Blind flanges seal off the end of pipes either permanently or temporarily and do not have any holes or openings. Threaded flanges have tapered threads on their inner surface which allows them to be securely fastened onto pipes with threads cut into them. Weld neck flanges have longer necks than other types, allowing for easy welding to pipes without worrying about unevenness or misalignment between them. Lap joint flanges have two pieces that can easily be attached with bolts or screws for added convenience and ease of installation.


Duplex S31803 Flanges are commonly used in applications that require high strength and corrosion resistance, such as oil and gas processing, chemical processing & marine environments. They offer good resistance to stress corrosion cracking, pitting & crevice corrosion.
The advantages of Duplex S31803 Flanges include their high strength and resistance to corrosion, as well as their excellent toughness and ductility. They also offer good weldability & machinability, making them easy to work with.
Duplex S31803 Flanges are pipe fitting made from grade S31803 duplex stainless steel. These flanges are designed to provide a strong and reliable connection between two pipe sections or between a pipe & a valve, pump, or other equipment.
