DESCRIPTION OF HASTELLOY C-276

Hastelloy® C-276 is a very versatile nickel-molybdenum-chromium-tungsten alloy with excellent corrosion resistance and good fabricability. While it does have good oxidation resistance up to 1800°F, Hastelloy alloy C-276 is generally not recommended for elevated temperature service.

Nickel Alloy C-276 has resisted the formation of grain boundary precipitates in the weld-heat affected zone, making it a candidate for most chemical and petrochemical processing applications in the as-welded condition. HC276 is a nickel alloy that is has excellent resistance to reducing acids, sulfuric acid, hydrochloric acid, brine solutions, oxidizing chlorides, and hot seawater.

Hastelloy C-276 is also one of the few materials resistant to wet chlorine gas, hypochlorite and chlorine dioxide. This particular nickel alloy has exceptional resistance to crevice corrosion and stress corrosion cracking, as well as chloride pitting. It's low carbon content minimizes carbide precipitation during welding preserves its excellent resistance to corrosion during welding. This translates to C-276 being readily fabricated by welding using methods similar to those utilized for nickel-based alloys.

Hastelloy C-276 is also known as:

  • Nickel C-276

  • Alloy C-276

  • Inconel C-276

ADDITIONAL PROPERTIES

HASTELLOY C-276 CORROSION RESISTANCE DATA

HASTELLOY C-276 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 hot contaminated mineral acids, ferric and cupric chlorides,solvents, chlorine and chlorine contaminated (both organic and inorganic), dry chlorine, acetic anhydride, formic and acetic acids, sea water and brine solutions, chlorine dioxide solutions, and hypochlorite.

For more information on Alloy C276 refer to NACE (National Associate of Corrosion Engineers) for recommendations.

AVAILABLE FINISHES FOR HASTELLOY C276

#1Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D
Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2BSmooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#CBACourse bright annealed cold rolled matte finish and bright anneal
#2Cold Rolled
#2BASmooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part
