ASTM A789/A790 Duplex Pipes, Tubes

Duplex Steel Pipes Suppliers, Duplex Steel Tubes, Austenitic and Ferritic Duplex Steel Pipes and Tubes Dealers.

Stolt Alloys FZE is a known stockist and trader and offers a wide range of ASTM A789 Duplex 2205 Pipes and Tubes, which is the most widely used duplex stainless steel grade.ASTM A789 Duplex 2205 Tubes is a duplex (austenitic-ferritic) stainless steel containing about 40 – 50 percent ferrite in the annealed condition.ASME SA 789 Duplex 2205 Pipes integrates the best features of austenitic and ferritic steels (as well as nearly equal amounts of austenite and ferrite) and can be welded with common stainless steel welding techniques – its uniform composition minimizes localized corrosion. ASME SA 789 Duplex 2205 Tubes is designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion. ASTM A790 Duplex 2205 Pipes resists chloride environments and sulfide stress corrosion. ASME SA 790 Duplex UNS S31803 Tubes also resists localized corrosion types like intergranular, crevice and pitting. Buy Duplex Stainless Steel Pipes and Tubes at affordable rates from us.
