Who manufactures Hastelloy C276 seamless pipe?
Gnee Steel is one of the large manufacturers of high quality Hastelloy C276 pipe and tube. The high molybdenum content of Hastelloy C276 pipe gives it excellent resistance to crevice corrosion and pitting in a variety of processing environments. C276 Hastelloy seamless pipe is designated as UNS N10276 and Werkstoff number 2.4819. Hastelloy C276 welded pipe is capable of being welded by most commonly used welding methods. Excessive heat input should be avoided during the Hastelloy C276 ERW pipe welding process. SCH40 Hastelloy Alloy C276 clad pipe, Hastelloy C276 pipe, and Alloy C276 welded pipe perform very well in extreme conditions, alleviating any operator concerns about possible failures.


Hastelloy C276 pipe is hardened only by cold working. Hastelloy C276 Seamless Tube, Alloy C276 Gas Tube and Hastelloy C276 Polished Tube are also used at high temperatures and high mechanical stresses and where high surface stability is required. Hastelloy C276 boiler tubes exhibit excellent resistance to mineral acids, even in welded form. Hastelloy C276 Seamless Tube is designated Werkstoff No. 2.4819 and UNS N10276.
