Duplex Stainless Steel Pipe ASTM A789 / ASTM A790 / ASTM The duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels. However, the corrosion resistance of the least resistant duplex stainless steels is greater than that for the most commonly used grades of stainless steels, i.e. 304 and 316. Duplex

Stainless Steel Duplex 2205 Buttweld Fittings ManufacturersManufacturing Stainless Steel Duplex 2205 buttweld fittings A Stainless Steel Duplex 2205 buttweld pipe fitting is made by the process of hot forming that includes bending and forming to shape. The starting material of butt weld fitting is a pipe that is cut to length, heated and molded into specific shapes by means of dies.
Type 2205 duplex stainless steel is a grade that offers very good pitting and uniform corrosion resistance, high strength and high resistance to stress corrosion cracking. Typical applications for duplex alloys are heat exchangers, tubes, pipes, pressure vessels and tanks in
