WHAT IS DUPLEX STAINLESS STEEL?
Duplex Stainless Steel Tube is a type of austenitic stainless steel that comprises of nickel and chromium majorly, along with other elements like nitrogen and molybdenum. This stainless steel alloy offers good resistance to localized as well as to uniform corrosion. The duplex microstructure of the alloy contributes to the high strength and high resistance to stress corrosion cracking. It has good weld ability and offers many beneficial properties of ferritic and austenitic steels combined.
Duplex Stainless Steel gives very good resistance to pitting and crevice corrosion and has high resistance to stress corrosion cracking and corrosion fatigue. It displays high mechanical strength and also provides good abrasion and erosion resistance. It is used in chemical, Oil and gas and marine industries. Other uses if duplex stainless steel is in pollution control equipments, pulp & paper manufacturing, seawater desalination plants and in flue-gas cleaning to name a few.

INTRODUCTION ABOUT DUPLEX STAINLESS STEEL TUBES
Duplex Stainless Steel Tubes are highly strong tubes that put up great resistance against stress corrosion cracking. These tubes are suitable for environments with exposure to difficult environments. They are extremely durable and perform well under stressful conditions. Due to the content of chromium, nitrogen and molybdenum, Duplex Stainless Steel Tubes offer good resistance to local and uniform corrosion. These Duplex Stainless Steel Tubes have high resistance to stress corrosion cracking and corrosion fatigue and are good at sulphide stress corrosion resistance. They also have good weld ability and are useful in a variety of industries.
Duplex Stainless Steel Tubes are utilised in a list of applications including chemical processing, transport and storage, oil and gas exploration and offshore rigs, oil and gas refining, marine environments, pollution control equipment and pulp & paper manufacturing. Other uses of these tubes are in flue-gas cleaning, desalination plants and seawater systems, bridges, storage tanks, pressure vessels, reactor tanks, and heat exchangers.
