Hastelloy C-276 has a excellent resistance to localized corrosion, stress corrosion cracking, oxidizing and reducing media, which is suit for a wide variety of chemical process environments, including ferric and cupric chlorides, hot contaminated media (organic and inorganic), formic and acetic acids, seawater and brine solutions. Meanwhile, Hastelloy C276 is the few kinds of material that can withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.
Alloy C-276 is a solid solution strengthened nickel-molybdenum-chromium alloy with a small amount of tungsten. Alloy C-276 exhibits excellent corrosion resistance in a variety of harsh environments and media. Like many other nickel alloys, it is ductile, easily formed and welded.

Standard Specification for Forged or Rolled Nickel Alloy Pipe Flanges, Forged Fittings, and Valves and Parts for Corrosive High-Temperature Service
Abstract
This specification covers forged or rolled UNS N06030, UNS N06035, UNS N06022, UNS N06200, UNS N06059, UNS N06686, UNS N08020, UNS N08024, UNS N08026, UNS N08367, UNS N10276, UNS N10665, UNS N10675, UNS N10629, UNS N08031, UNS N06045, UNS N06025, and UNS R20033 alloy pipe flanges, forged fittings, and valves and parts intended for corrosive high temperature service. A sufficient discard shall be made from each ingot to secure freedom from injurious piping and undue segregation. Requirements for forging (done by hammering, pressing, rolling, extruding, or upsetting), hot working, and heat treatment are detailed. The material shall conform to the chemical composition prescribed for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, columbium, tantalum, nitrogen, iron, cobalt, tungsten, vanadium, titanium, zirconium, aluminum, yttrium, and cerium. The material shall meet the requirements specified for the mechanical properties including tensile strength, yield strength, and elongation. The forgings shall conform to the specified sizes and shapes. Requirements for chemical and product (check) analyses and hydrostatic, macroetch, and tension tests are given.
