What is a Super Duplex Stainless Steel Pipe?

Super duplex stainless steel has all of the same benefits as its counterpart, the main difference being that this metal has a higher chromium and molybdenum content, which provides it with increased corrosion resistance. Super duplex stainless steel is often employed in the oil and gas industry, heat exchangers, offshore platforms, chemical processing equipment, boilers, and pressure vessels. The high chromium and molybdenum content of super duplex makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Super duplex also provides excellent resistance to inorganic acids, especially those containing chlorides. Super duplex stainless like S32750, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.

Inspection & Testing of Super Duplex Stainless Steel Pipes

• Mechanical Testing Such as Tensile of Area, Hardness Test, Positive Material Identification – PMI Testing, Flattening Test, Micro and Macro Test, Pitting Resistance Test, Flaring Test, Intergranular Corrosion (IGC) Test.

Metline is a large producer of various type of super duplex stainless steel pipes such as seamless pipes, welded pipes, ERW pipes types. We produce and forge super duplex stainless steel pipes to specifications of ASTM A249, ASTM A269, ASTM A213, ASTM A312, ASTM A790. Super duplex steels are easily welded and formed, similar to austenitic grades. Super duplex stainless steel comes in varied shapes & specifications like round bars which have a higher strength & ductility. Its categorically high marine corrosion resistance makes it a first choice for oil & gas & marine industries.

Features of Duplex Stainless Steel Pipes
