ASTM B 622 Hastelloy Alloy C-276 Seamless Pipe for Oil and Gas Service
Description:
Inconel C-276 (UNS N10276 / W. Nr. 2.4819, NS334) is known for its corrosion resistance in a wide range of aggressive media. The high molybdenum content imparts resistance to localized corrosion such as pitting. The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints. It is used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of “sour” natural gas. Applications in air pollution control include stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans and fan housings. In chemical processing, the alloy is used for components including heat exchangers, reaction vessels, evaporators and transfer piping.

About Hastelloy C-276
Hastelloy C-276, which is also sold as Nickel Alloy C-276, is a nickel-molybdenum-chromium wrought alloy. Hastelloy C-276 is perfect for use in situations that demand protection from aggressive corrosion and localized corrosion attack. This alloy Other important features of Nickel Alloy C-276 and Hastelloy C-276 include its resistance to oxidizers like:
● Ferric and cupric chlorides
● Organic and inorganic hot contaminated media
● Chlorine (wet chlorine gas)
● Seawater
● Acids
● Hypochlorite
● Chlorine dioxide
