The UNS S31803 fittings consist of duplex stainless steel, with equal portions of austenite and ferrite microstructure.
The UNS S31803 Pipe Fittings has two phases and comprises ferritic, austenitic, 22 % chromium, 3 % molybdenum,
5 to 6 % nickel alloyed stainless steel. We are one of the top manufacturers of ASTM A815 UNS S31803 Fittings in China,
known for its quality, strength, and durability. Our productions, like Duplex Steel S31803 Buttweld Fittings, are customizable
according to the requirements of our esteemed clients and made with accuracy. We believe in timely delivery and never
compromise with that. We manufacture a wide range of products, including:
- The Duplex S31803 Elbow is used to change the direction or the angle of the pipe run.
- Our Duplex 2205 1.4462 Pipe Reducer helps reduce the pipe bore size from a bigger to a smaller one.
- We also manufacture the S31803 Duplex Steel End Cap, which protects the ends of the pipe and other fittings.
- They are available in different shapes according to the shape of the pipe.
- We supply UNS S31803 Duplex Steel Welded Tee mainly used for combining or diving the flow. It also helps to connect
- pipes with different diameters.
Duplex stainless steels are a family of stainless steels. These are called duplex (or austenitic-ferritic) grades because their
metallurgical structure consists of two phases, austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice)
in roughly equal proportions. They are designed to provide better corrosion resistance, particularly chloride stress corrosion
and chloride pitting corrosion.Duplex stainless steel UNS S31803 (and the other specifications listed below) is described as
a duplex stainless steel with a microstructure of 50:50 austenite and ferrite. The steel combines good mechanical strength
(typically up to over 480 MPa yield strength) and ductility with moderate to
good corrosion resistance in a variety of environments.
