We are the Suppliers of Super duplex stainless steel .It differs from duplex in that it is a steel with pitting corrosion resistance. They are a highly alloyed steel often with 25% chromium or more. They have the same high strength and resistance to stress corrosion, fatigue and erosion as duplex as well as offering a great resistance to chloride elements that can cause stress corrosion cracking. Couple this with a high thermal conductivity rate as well as a low coefficient of thermal expansion and super duplex quickly becomes the stainless steel of choice for many.

Question - What is Duplex Steel Pipe?
Nascent Pipe and Tubes is one of the leading Manufacturers, suppliers, exporters, traders and stock holders of Duplex Steel Pipe. Duplex Steel Pipes and Tubes are available in various dimensions, shapes like square, rectangle, and so on and enormous sizes. We are offering the standard quality of products of our customers. Our Product is offering excellent corrosion resistance and remarkable dimensional accuracy. We also are customizing our products in various specifications, sizes, grades, and thicknesses as per the client’s demand. These Duplex Steel Pipe and Tubes have enormous applications in many industries. These Duplex Steel Seamless Pipes and tubes are highly alloyed with different metals and having excellent mechanical strength. These Duplex Steel Pipes are used in multi-purposed operations and possess good weldability used highly in the marine industry and offshore. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance).
Duplex Steel Pipe -
Nascent Pipe and tubes is a renowned manufacturer and supplier of Duplex Steel Pipes & Tubes. We have been a part of this industry for long and our high-quality product is in use for many years. We have been serving pipes and tubes needs of a large number of industrial clients with our superior products. Duplex Steel Pipe and tubes is a microstructure of austenite and ferrite. Hence it has improved strength over other steel grades. This has high strength and effective resistance to pitting. It is resistant to stress corrosion cracking and fatigue. This makes it suitable for welding applications. The most common way adopted for welding is tungsten arc welding. These are equally compatible with forming applications as well.
