Hastelloy C276


Mahesh Enterprises is India’s one of the leading Fasteners manufacturers & Suppliers in Hastelloy C276 in Nickel 200/201, Monel 400, Inconel 600/625, Incoloy 800 ,800H & 800HT, Hastelloy C22/Hastelloy C276, Alloy 904 L/Alloy 20, Ti Grade 1/2/3/4/5/7. It is a nickel-molybdenum-chromium with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. High nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Although there are several variations of the Hastelloy nickel alloy, Hastelloy C276 is by far the most widely used.

Alloy C276 is widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.

Corrosion Resistant Hastelloy C276

Considered one of the most versatile corrosion resistant alloys available, Hastelloy C-276 exhibits excellent resistance in a wide variety of chemical process environments including those with ferric and cupric chlorides, hot contaminated organic and inorganic media, chlorine, formic and acetic acids, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions. In addition, alloy C-276 resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. This alloy has excellent resistance to pitting and stress corrosion cracking.
