Duplex steel seamless tube is a type of stainless steel tube made from a material that is a combination of austenitic and ferritic stainless steel. This type of steel provides superior corrosion resistance, strength, and superior weldability compared to other stainless steel materials. Duplex steel seamless tubes are used in a wide variety of applications ranging from petrochemical and oil and gas to food processing and transportation. Duplex steel seamless tubes offer superior performance in extreme environments and are preferred for their superior corrosion resistance, high strength-to-weight ratio, and superior weldability.
