Alpha Overseas(AOS) is identified as a manufacturer of Duplex Steel S31803 / S32205 Butt Weld Pipe Fittings, which is the most widely used duplex (ferritic and austenitic) stainless steel grade. Duplex S31803 Butt Weld Pipe Fittings has Good weldability in thick plates and Good low temperature toughness. Duplex S31803 Pipe Fittings are extremely corrosion resistant and work hardenable alloys. Duplex Steel S31803 Butt Weld Fittings has high broad corrosion conflict, pitting and crack corrosion confrontation superior to austenitic SS 317L. Duplex S32205 Butt Weld Pipe Fittings is nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. Duplex S32205 Pipe Fittings is a duplex stainless steel with a 50:50 austenite and ferrite microstructure. Duplex S32205 Butt Weld Fittings is the most common duplex grade in the market, which is ideally suited for high-pressure and highly corrosive environments.
These UNS S31803 Butt Weld Pipe Fittings are actually are available in four groups that include martensitic, ferritic, austenitic, and precipitation-hardened steels, which are formed based on the crystalline structure of stainless steels. High temperature strength of UNS S32205 Butt Weld Pipe Fittings is similar to SS 430 in the range of 950 Degree C to 1150 Degree C. UNS S31803 Pipe Fittings is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite. UNS S32205 Pipe Fittings is a nitrogen-enhanced stainless steel.
Duplex Steel S31803 Buttweld Pipe Fittings is made from superior quality Raw Material and are available in Customized Designs to suit different requirements of the clients. Our contemporary technology and constant efforts to acquire new skills to enhance production is the secret of our success and impeccable quality.
