Audited Supplier The Hastelloy C276 Pipe is covered by 2 specifications i.e. ASTM B622 as well as ASTM B619. Typically the ASTM B622 Pipe is constructed in a seamless manner, whereas the construction of the ASTM B619 Pipe is welded. Amongst all the Hastelloy variations the C276 Hastelloy Pipe is the most popular one.
The low content of carbon in the 2.4819 Alloy C276 Pipe is what minimizes carbide precipitation. Carbide precipitation is a phenomenon that occurs during welding of various alloy grades. A lower carbon based alloy such as the ASTM B619 UNS N10276 2.4819 Pipe is used in several applications which have the need to maintain its corrosion resistance properties in as-welded structures. This specified nickel Hastelloy C276 Seamless Pipe is also resistant to the formation of grain boundary precipitates, especially its occurrence in the weld heat-affected zone. Thus the Hastelloy C276 Welded Pipe is well suited to be used in chemical process application in an as-welded condition. By adding tungsten in the ASTM B622 UNS N10276 Alloy C276 Pipe, its corrosion resistance properties become superior. For example, the ASTM B622 UNS N10276 Pipe exhibits excellent resistance to pitting and crevice corrosion in both reducing and oxidizing environments. Alloy C276 Seamless and Welded Pipes are available in many types such as Square, Round and Rectangular.
We offer corrosion resistant Alloy C-276 seamless and welded pipe in standard, in various wall thicknesses from schedule 10 to schedule XS. We can supply custom pipe sizes, including large and small O.D. and heavy or thin wall per your request. Further processing options include drilling, boring, milling and threading.
