Why Hastelloy C276 Plates Outperform Competitors
Hastelloy C276 (UNS N10276, ASTM B575) is a nickel-molybdenum-chromium alloy enriched with iron and cobalt, engineered to resist pitting, crevice attack, and stress corrosion cracking in some of the world's most aggressive chemical conditions. It is used extensively in heat exchangers, reactors, and pollution control equipment within power plants and chemical facilities.
The alloy excels in high temperature environments (up to 1100°C) while maintaining mechanical stability and corrosion resistance in hydrochloric, sulfuric, and other aggressive acid media. Its composition offers superior weldability and fabrication ease compared to other corrosion-resistant alloys, reducing downtime and enhancing project lifecycle economics.
Aurico Alloys LLP guarantees delivery of certified Hastelloy C276 Plates compliant with ASTM B575, ISO standards, and NACE MR0175 certifications. Our stock and processing capabilities ensure fast shipping, precision cutting, and documentation for global project and regulatory compliance.

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.
- Chemical reaction vessels, heat exchangers, and piping systems
- Pollution control equipment including flue gas desulfurization units
- Marine seawater handling systems and desalination plants
- Oil & gas sour gas service and acid gas removal components
- Pharmaceutical processing tanks and sterilizers
- Power plant boilers, superheaters, and high-temperature ductworks
