Super Duplex 2507 (UNS 32750) Seamless Welded PIpes Tubes Tubing
Duplex Steel 2507 Seamless Welded PIpes Tubes Tubing : Agent, Dealer, Distributor, Exporter, Stockist, Stockholder and Supplier in India :
Super Duplex 2507®, is very similar to UNS S31803 2205® Duplex. The difference between the two is the contents of chromium and nitrogen are higher in the 2507® which in turn creates higher corrosion resistance as well as a longer lifespan. 2507® is composed of between 24% to 26% chromium, 6% to 8% nickel, 3% molybdenum, and 1.2% manganese, with the balance being iron. Trace amounts of carbon, phosphorus, sulfur, silicon, nitrogen, and copper are also found. Benefits include good weldability and workability, a high level of thermal conductivity and low coefficient of thermal expansion, resistance to corrosion, fatigue, pitting and crevice corrosion, high resistance to stress corrosion cracking especially in chloride atmospheres, high energy absorption. Essentially, the Duplex alloys are a compromise; possessing some of the ferritic stress corrosion cracking resistance and much of the superior formability of the common austenitic stainless steel alloys yet more cost effective than the high nickel alloys.
Since 2008, there has been a major demand for Duplex Steel Seamless Welded PIpes Tubes Tubing due to its excellent corrosion resistance quality. It resists inter-granular and crevice corrosion. It also shows appreciable resistance to pitting. Chloride stress corrosion cracking is also dealt with easily using Duplex 2507, at a temperature of 150 degree Celsius. It proves to be an excellent substitute of austenitic grades in marine environments. It shows good thermal resistance up to a range of 300 degree Celsius. It can be easily welded by most of the standard methods, the only compulsion being the use of filler metals. The machinability is low on account of its high strength.and Citizen Metals has been actively involved in ensuring the best quality of the same to our clients.
This exotic alloy is used in oil and gas exploration, chemical processing industries also make use of this alloy. Most of the processing equipment utilizes Duplex 2507. It is also used by storage and transportation units of industries. Pulp and paper digesters, liquor tanks and paper machines also use Duplex 2507. It is highly suitable for usage in marine environments
