UNS Number N10276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The 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, UNS Number N10276 is by far the most widely used.
 
UNS Number N10276 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.
Available Form:
Sheet , Plate , Pipe & Tube (welded and seamless) , Wire , Fittings

Corrosion Resistant
Considered one of the most versatile corrosion resistant alloys available, UNS Number N10276 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, UNS Number N10276 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.
Fabrication with UNS Number N10276
UNS Number N10276 alloy can be forged, hot-upset and impact extruded. Although the alloy tends to work-harden, you can have it successfully spun, deep-drawn, press formed or punched. All of the common methods of welding can be used, although the oxyacetylene and submerged arc processes are not recommended when the fabricated item is for use in corrosion service.
UNS Number N10276 Welding Material
UNS Number N10276 welding products are used as matching composition filler material for welding C276 alloy wrought and cast products, for dissimilar welding applications including other nickel-chromium-molybdenum alloys and Stainless steels, and for weld overlay or cladding of steels.

UNS Number N10276 is a nickel-chromium-molybdenum alloy with universal corrosion resistance unmatched by any other alloy. It has outstanding resistance to a wide variety of chemical process environments including ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine and chlorine contaminated (both organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, sea water and brine solutions and hypochlorite and chlorine dioxide solutions. UNS Number N10276 also resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. It has excellent resistance to pitting and stress corrosion cracking.
UNS Number N10276 sheet 0.044" thick in the heat-treated condition at 2050°F, rapid quenched, has an average olsen cup depth of 0.48". UNS Number N10276 can be successfully fabricated by many methods. The alloy tends to work harden but with the proper care, the alloy is readily hot and cold formed. Complete information on welding, machining and forming is available.

Characteristic
1. Excellent corrosion resistance in reducing environments
2. Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides
3. High nickel and molybdenum contents providing good corrosion resistance in reducing environments
4. Low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints
5. Resistance to localized corrosion such as pitting and stress-corrosion cracking
6. One of few materials to withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide

Application:
1. Digesters and bleach plants in the paper industry.
2. Components exposed to sour gas.
3. Equipment for flue-gas desulfurisation plants.
4. Evaporators, heat exchangers, filters and mixers used in sulfuric acid environments.
5. Sulfuric acid reactors.
6. Organic chloride process equipment.
7. Equipment for processes utilizing halide or acid catalysts.
Some typical applications include equipment components in chemical and petrochemical organic chloride processes and processes utilizing halide or acid catalysts. Other industry applications are pulp and paper (digesters and bleach areas), scrubbers and ducting for flue gas desulfurization, pharmaceutical and food processing equipment.
