Hastelloy C276 Pipe Fittings is one of the most widely used fittings, amongst the other Hastelloy variants. Since these fittings have excellent performance in the most severe environments, the Hastelloy C276 Stub End is regularly a part of industries such as chemical processing, pollution control, industrial and municipal waste treatment, as well as pulp and paper production and recovery of sour natural gas.

Alloy C276 Elbow
B366 UNS N10276 Stub end
Additionally, the Alloy C276 Elbow is one of few fittings that has the ability to withstand the corrosive effects of not only wet chlorine gas, but also hypochlorite and chlorine dioxide. The Hastelloy C276 Reducer resists the formation of grain boundary precipitates, due to the low content of carbon in the alloy especially in the heat affected welded zone, thereby proving to be quite useful for most chemical processes in the as welded condition.

Hastelloy C276 Fittings
The Hastelloy C276 Elbow also has excellent resistance to localized attack like pitting as well as crevice corrosion, particularly in reducing environments. When exposed to oxidizing media, the content of chromium in the ASTM B366 UNS N10276 Stub end is what imparts its resistance to corrosion. The superalloy Hastelloy C276 Fittings are also resistant to SCC or stress related corrosion cracking.
