China Super Duplex Stainless Steel Pipe S32750

China Super Duplex Stainless Steel Pipe S32750 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication. The high contents of elements chromium, molybdenum, and nickel are what provide the China Super Duplex Stainless Steel Pipe S32750 with excellent resistance to local corrosion such as pitting and crevice corrosion, as well as general corrosion.

Due to China Super Duplex Stainless Steel Pipe S32750 chemical composition with regards to its highest alloyant content, this grade is also referred to as 25cr super duplex tube. This particular grade of China Super Duplex Stainless Steel Pipe S32750 is famous for its excellent resistance to chloride-ion stress-related corrosion cracking, which has been attributed to the duplex microstructure of the alloy. The fractional alloy 2507 super duplex tubing, also has a high thermal conductivity in addition to having a low coefficient of thermal expansion.

The higher content of chromium and molybdenum in the China Super Duplex Stainless Steel Pipe S32750 makes it extremely resistant to uniform corrosion in the presence of organic acids like formic and acetic acid. China Super Duplex Stainless Steel Pipe S32750 material can be used in dilute hydrochloric acid as well. In fact, China Super Duplex Stainless Steel Pipe S32750 offers excellent resistance to inorganic acids, especially in those settings which contain chlorides.
