stainless steel pipe is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'.

This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.

stainless steel pipe also contains varying amounts of Carbon, Silicon and Manganese.

Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.

Natural Steels is the most acclaimed manufacturer, exporter, importers and supplier of industrial Duplex Stainless Steel Pipes & Tube. Our valued customers in different grades, lengths and thickness. These pipes are resistant to corrosion and are widely appreciated in the market.

We offer qualitative these Duplex Steel Seamless Pipes in different sizes and shapes that are being designed as per the national and international standard quality of raw materials.

Duplex is a mixed microstructure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. The chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively.

Super duplex pipes produced under specification ASTM A790, are supplied in a seamless or a welded construction. The automatic process used to manufacture Super Duplex Welded Pipe is without the use of a filler metal. The Super Duplex Pipe suppliers recommend using these pipes for applications that are prone to general corrosion resistance. There are several reasons that account for the corrosion resistance properties of the ASTM A790 UNS S32760 pipe. In addition to having a high content of molybdenum, nickel and chromium, there is a significant inclusion of austenite stabilizing element, nitrogen. A heat analysis is performed on the ASTM A790 UNS S32750 in order to determine the proportion of the elements specified herein. 

Next, the mixed microstructure of the Super Duplex 2507 Pipe enhances its properties. For instance, the ferritic part of the duplex microstructure in the alloy of the pipe is responsible for the Super Duplex 2507 Seamless Pipe exhibiting superior resistance to stress related corrosion cracking, particularly when exposed to warm chloride ion bearing circumstances. Generally, tests such as flattening tests, hardening tests, hydrostatic tests, Tension tests and nondestructive electric tests are performed on the Super Duplex Seamless Pipe to ascertain their conformance to the ASTM A790.

Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

Usage of Duplex 2507 should be limited to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.

Duplex 2507 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.

2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid. It is alsohighly resistant to inorganic acids, especially if they contain chlorides.  Alloy 2507 is highly resistant to carbide-related intergranular corrosion.  Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.
