Guanyu Tube is Specialized Manufacturer of Duplex stainless steel pipe (DSS). ASTM A789 SA789 S31803 S32205 2205 Duplex Tubes and ASTM A790 SA790 S31803 S32205 2205 Duplex Pipes. Duplex Steel is featured with structure of two phases ( and ) and has characteristics of both ferritic and austenitic stainless steel.
A Guide to Duplex Stainless Steel What is It? - Unified Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses.
Super-Duplex falls under the Duplex stainless steel grouping. Duplex stainless steels are graded for their corrosion performance depending on their alloy content. Today, modern Duplex stainless steel can be divided into four groups: Lean Duplex such as 2304, which contains no deliberate Mo addition; 2205, the work-horse grade accounting for

China Cheap Duplex Stainless Steel Pipe Suppliers 1.4462 Duplex Stainless Steel Pipe. 1.4462 is a duplex stainless steel with nearly equal proportions of austenite and ferrite when properly heat treated. This microstructure makes it much more resistant to stress corrosion cracking than stainless steel 304 and 316L. 1.4462's higher chromium, molybdenum and nitrogen contents give it significantly
The chemical composition of 2205 Duplex Stainless Pipe consists of the elements being used in the following content i.e. - 22% chromium, 3% molybdenum and about 5 to 6% nickel. Because of the content, in terms of quantity of chromium present in the alloy of this grade, this stainless steel is also referred to as 22cr Duplex 2205 Pipe.
