ASTM B564 UNS N10276 Hastelloy C276 Nickel Alloy Flange SORF Flange
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.
It 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.
What are the characteristics of Hastelloy C276?
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

Applications & Uses of Hastelloy Alloy Flanges
Although there are several variations of the Hastelloy nickel
alloy, Hastelloy C-276 is by far the most widely used.
Alloy C-276 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.
Hastelloy C276 Flange are mainly used in Oil & Gas, Chemical,
Nuclear power (mostly seamless), Power, Bitumen upgraders,
Petrochemicals and acids, Heavy oil refineries, Gas, ,Construction,
Shipbuilding industries, Metallurgy&others.
