Hastelloy C276 is an austenitic superalloy grade that has nickel, molybdenum and chromium in its chemical composition. The n Hastelloy c276 pipe shows good resistance to oxidation and corrosion in different types of environments. They also have a good tolerance to pitting and crevice corrosion in reducing solutions and can operate within the temperature range of 1900 °F. The alloy C276 exhaust pipe has a high melting point of 1371 °F and thus, they are ideal for high temperature applications.
The Hastelloy alloy C276 annealed pipe is known for its high strength and cannot be hardened by heat treatment process. They are annealed at 1121 °F, after which they undergo quenching. Due to all these properties, the DIN 2.4819 clad pipe can be used in critical industries like gas processing, specialty chemicals, pharmaceutical equipment, etc. They show good resistance to chloride ion related stress corrosion cracking and can be used in seawater equipment.

The hot working temperature range for UNS N10276 pipe is 1600-2250 °F. The material should be quenched after hot working. The Hastelloy 2.4819 seam welded pipe should undergo heat treatment to maximize their corrosion resistance properties. The operating temperature of UNS N10276 cold drawn pipe ranges from cryogenic to 2012 °F. The specific range will however depend on environment, pressure and various other factors.
The Hastelloy c276 pipe manufacturers produces the welded pipes for sour gas wells and Pollution control stack lines, stack gas reheaters, scrubbers, etc. The nickel alloy C276 welded pipe is widely used in flue gas desulfurization system. They are found in heat exchangers, reaction vessels, etc. in industries like chemical processing, waste treatment, etc.
