On a coastal refinery where sour gas, wet chlorine and hot seawater meet in the same pipe rack, a set of conventional stainless steel gaskets began to pit and leak after just eight months, forcing an emergency shutdown and millions in unplanned losses. The engineering team replaced those failing components with precision-cut Hastelloy® Foil linings and gaskets in UNS N10276 and UNS N06022, and service life immediately jumped by several years with no signs of pitting, crevice attack or weld decay in aggressive mixed-acid conditions . For procurement heads, maintenance engineers, fabricators, OEMs and industrial hardware stores in chemical, oil & gas, marine, pharma and power generation, that kind of reliability is the difference between constant firefighting and predictable uptime.
Table of Contents:
Hastelloy C276 foil (UNS N10276) is a nickel‑chromium‑molybdenum‑tungsten alloy renowned as a “universal” corrosion‑resistant material, with tested tensile strength around 790 MPa, yield strength ~355 MPa and elongation ~40% at room temperature, plus excellent resistance to reducing acids, wet chlorine, hydrochloric and sulfuric acids, brine and hot seawater . Hastelloy C22 foil (UNS N06022) raises the bar for oxidizing and chloride‑rich environments, delivering highest‑in‑class pitting and crevice corrosion resistance for pharmaceutical processing equipment, multi‑purpose reactors and clean‑in‑place systems where 316L, 904L or even Alloy 20 cannot cope with modern CIP chemistries . Compared with Inconel 625 foil, which is excellent but more optimized for high‑temperature strength than universal wet‑corrosion service, Hastelloy foils consistently offer broader resistance in strongly reducing acid systems and complex mixed media, cutting lifecycle cost even if the initial price per kg is slightly higher .
Aerospace‑grade Hastelloy X foil (UNS N06002) combines oxidation resistance, fabricability and high‑temperature strength, remaining ductile even after 16,000 hours at 650–870°C in gas turbine combustion liners and honeycomb seals, making it a go‑to choice for engine OEMs and MRO facilities worldwide . Hastelloy C2000 foil (UNS N06200) adds a deliberate copper content to the Ni‑Cr‑Mo base, boosting resistance in sulfuric, hydrofluoric and dilute hydrochloric acids, which is invaluable for thin‑gauge sensor shields and electronics exposed to aggressive chemical vapors in process plants . For extreme reducing acid duties, Hastelloy B3 foil (UNS N10675) offers extremely high resistance to pure hydrochloric, hydrobromic and sulfuric acids with improved thermal stability over older B2 versions, making it suitable for vacuum furnace linings and pickling equipment where temperature excursions are unavoidable .
Aurico Alloys LLP positions Hastelloy® Foil as an affordable yet high‑assurance solution, supplying authentic coils and cut‑to‑size strips with full EN 10204 3.1 MTCs, PMI testing and global export packing for chemical, oil & gas, marine, pharma, power producers and industrial supply houses seeking a trusted supplier, manufacturer and stockist in India. As Hastelloy foil exporters in Mumbai, the team supports applications from ASTM B575 Hastelloy C276 foil for specialized flue gas desulfurization systems to custom 0.01–2.0 mm gauges for subsea components and sour‑gas refineries needing guaranteed corrosion performance and traceability .
