    Detailed Information
    Duplex Steel S31803 Butt Weld Fitting is made from a blander with high Nickel, Chromium, and Molybdenum content, which provides excellent corrosion resistance in a variety of environments. The Duplex Steel S31803 Butt Weld Fitting’s high Nickel and Chromium content improved resistance to pitting, stress corrosion, high strength crevice corrosion, and cracking. It is also highly resistant to stress corrosion cracking and localised corrosion. Furthermore, the mechanical properties of this Duplex Steel S31803 Butt Weld Fitting are exceptional. Because this austenitic grade is both economical and dependable, it has a long working life. Aside from that, Duplex Steel S31803 Butt Weld Fitting has excellent workability and weldability.
    The Duplex 2205 Buttweld Fittings are a popular duplex stainless steel grade material that has a yield strength that is nearly double that of standard austenitic stainless steel grades. Furthermore, the UNS S31803 Buttweld Pipe Fittings that we provide have an excellent fatigue strength as well as an outstanding resistance to stress corrosion and cracking. It has superior corrosion resistance properties due to its high chromium, molybdenum, and nitrogen content. They are also highly resistant to pitting and crevice corrosion in both oxidising and acidic solutions. In temperatures around 150 degrees Celsius, the Duplex 2205 Buttweld Pipe Fittings are resistant to chloride stress corrosion cracking. Duplex UNS S31803 Fittings perform well in caustic environments and have good weldability due to the presence of ferrite. Duplex 2205 is a two-phase ferritic, austenitic stainless steel with approximately 22% Cr, 3% Molybdenum, and (5 to 6% Nickel). Duplex steel buttweld fittings are also available in a variety of shapes and sizes, including 45 degree, 90 degree long and short radius elbows, equal and unequal tees, concentric and eccentric reducers, end pipe caps, stub ends, and many others. Their physical dimensions are determined by the various types of pipe fittings applications, which require varying shapes and sizes.
    Duplex Steel S31803 Butt Weld Fitting is widely used in many application industries such as Oil and Gas, Chemical Plant, Nuclear Power Projects, Heat Exchanges, Petrochemical Processing, Valves, and Pumps Manufacturing, Marine Field, Power Generation and others too.
