UNS N10276 Grade Overview
UNS N10276 (widely recognized as Hastelloy C-276) is a nickel-molybdenum-chromium superalloy fortified with tungsten. Engineered specifically to tackle the most demanding chemical environments, Alloy C276 offers exceptiona corrosion resistance in both reducing and oxidizing media.
Its unique chemical balance prevents grain-boundary precipitation in the weld heat-affected zone (HAZ), making it an ideal choice for complex welded chemical process equipment, pollution control installations, and marine chemical transport systems.
Key Highlights of UNS N10276
Excellent Corrosion Resistance:Outstanding performance in hydrochloric acid, chlorine, sulfuric acid and other aggressive environments.
Excellent Weldability:Low carbon content minimizes carbide precipitation, ensuring reliable welded performance.
Superior Pitting & Crevice Resistance:High molybdenum and tungsten content provides excellent resistance to chloride corrosion.
Reliable Chemical Stability:Maintains performance in oxidizing salt solutions and harsh chemical processing conditions.

Typical Application Scenarios of Hastelloy C-276
Engineers specify UNS N10276 across critical industries requiring reliable chemical containment and process safety:
Chemical & Petrochemical Processing: Reactors, heat exchangers, reboilers, evaporators, and piping systems handling organic and inorganic chlorides or mixed acid streams.
Flue Gas Desulfurization (FGD): Scrubber towers, reheaters, dampers, and duct liners exposed to aggressive acidic condensates in coal-fired power plants.
Pulp & Paper Manufacturing: Bleach plant equipment, chlorine dioxide bleach washers, digesters, and liquor heating systems.
Waste Treatment & Environmental Protection: Incineration scrubbers, hazardous waste processing vessels, and sour gas recovery units.
Pharmaceutical Synthesis: Reaction vessels, distillation columns, and high-purity fluid transfer components where contamination must be zero.
