Hastelloy® C276 UNS N10276 ASTM B575 Foil | Ultimate Corrosion Resistance
Table of Contents:
In the dead of night, a massive chemical plant in Gujarat faced catastrophe when hydrochloric acid lines failed under combined stress corrosion and high-velocity flow, threatening millions in downtime and environmental disaster. The fix? Hastelloy® C276 UNS N10276 ASTM B575 foil linings that not only sealed the breach but outperformed 904L, Alloy 20, and even Inconel 625 in reducing lifecycle costs by up to 40% through unmatched pitting and crevice resistance. Procurement heads, engineers, fabricators, OEMs, and hardware stores now specify Hastelloy C276 foil as the gold standard for chemical, oil & gas, marine, pharma, and power where inferior foils fail prematurely.

Why choose Hastelloy C276 foil over alternatives? Unlike Alloy 31 or duplex grades, C276 excels in oxidizing/reducing acid mixes and maintains ductility down to -196°C, reducing weld repairs by 60% in field fabrications. As a leading Hastelloy C276 foil supplier in Mumbai for pharmaceutical reactors and mixers, Aurico provides precision thicknesses (0.025mm to 0.1mm) ideal for burst discs, safety valves, and shim stock in UNS N10276 foil stockist for flue-gas desulfurization (FGD) scrubber linings.
Stats show Hastelloy C276 foil cuts maintenance by 35-50% in wet chlorine bleach plants versus 904L, per NACE studies, with corrosion rates under 0.1 mm/year in 10% HCl at 80°C. For ASTM B575 C276 foil price per kg in India for hazardous waste incineration filters, OEMs gain non-magnetic properties for marine sensors and high-purity surfaces for aerospace honeycombs.

Applications & Benefits
Why this grade
Hastelloy C276 carries roughly 16% chromium, 16% molybdenum and 4% tungsten, and it is the general-purpose member of the C family: it holds up in oxidising and reducing media alike, in wet chlorine, hypochlorite, seawater and flue-gas desulphurisation. It is the default C grade — move to C22 or C2000 only where a specific environment defeats it.
