Product Description

Hastelloy C-276 BA, Hastelloy C-276 (UNS N10276 / EN 2.4819) is the most widely used nickel-chromium-molybdenum alloy, often called the "universal" corrosion-resistant alloy. It offers exceptional resistance to a wide range of aggressive chemical environments, including oxidizing and reducing media, and is resistant to the formation of grain boundary precipitates in the weld heat-affected zone.

Hastelloy C-276 BA Tube Applications

Hastelloy C-276 BA tubes are widely used in the most severe corrosive environments where conventional stainless steels cannot provide adequate service life. Key application areas include:
·Chemical Processing — Heat exchangers, reaction vessels, evaporators, transfer piping, and components in organic chloride processes and processes utilizing halide or acid catalysts
·Petrochemical Industry — Equipment components in aggressive organic processes containing chlorides and catalytic systems
·Pollution Control — Stack liners, ducts, dampers, scrubbers, stack-gas reheaters, fans and fan housings
·Flue Gas Desulfurization (FGD) Systems — Absorber towers, piping, and associated equipment
·Pulp & Paper Production — Digesters and bleach plant areas
·Industrial & Municipal Waste Treatment — Processing equipment for corrosive waste streams
·Sour Natural Gas Recovery — Piping and components handling hydrogen sulfide-containing media
·Marine Engineering — Seawater and brine handling systems
