China 2205 Duplex Stainless Steel Tubing is a stainless steel tube. It belongs to a family of stainless steels called the duplex steels. There are different groups of this material. Alloy 2205 is ferritic-austenitic stainless steel used in situations that demand good corrosion resistance and strength. It is also referred to as Grade 2205 Duplex.
The 2205 duplex stainless steel pipe of this family could be formed either by the cold drawing of by hot rolling and welding. The China 2205 Duplex Stainless Steel Tubing is cold drawn and it has less absolute roughness. The seamless ones are less strong than the duplex SS 2205 welded tubing but are highly precise in dimension. The precision in dimension is useful in highly sensitive applications that require precision in measurements and calculations.
The combination of chromium, molybdenum, and nitrogen conveys the good resistance of China 2205 Duplex Stainless Steel Tubing to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed-loop water systems, and some food processing applications. The high chromium, molybdenum, and nitrogen contents of China 2205 Duplex Stainless Steel Tubing provide corrosion resistance superior to common stainless steel, such as 316L and 317L in most environments. Gaolin has been actively involved in ensuring the best quality of the same to our clients.
Features of China 2205 Duplex Stainless Steel Tubing:
