Nickel Alloys Alloy C276 Structural Profiles Overview
Zeon Exports supplies Nickel Alloy C276 (Hastelloy, UNS N10276) structural profiles – angles, channels and beams – a nickel-molybdenum-chromium alloy with tungsten addition offering exceptional resistance to both oxidizing and reducing corrosive media.
Nickel Alloy C276 (Hastelloy) Structural Profiles form load-bearing frames for chemical processing, pollution control and pulp & paper facilities. Its high molybdenum and tungsten content gives outstanding resistance to pitting, crevice corrosion and stress corrosion cracking in both oxidizing and strongly reducing environments, making it one of the most versatile corrosion-resistant structural materials available.
- Resists both oxidizing and reducing acids in a single alloy
- Tensile ≥690 MPa, yield ≥283 MPa in the annealed condition
- EN 10204 3.1 certified, export-ready worldwide

Corrosion Resistance of Nickel Alloys Alloy C276
Nickel Alloy C276 Structural Profiles resist an unusually broad range of corrosive media in a single alloy.
- Reducing acid resistance: excellent resistance to hydrochloric, sulfuric and phosphoric acids.
- Oxidizing resistance: performs well in wet chlorine, hypochlorite and other strongly oxidizing chemicals.
- Pitting and crevice resistance: high molybdenum and tungsten content gives outstanding resistance to chloride pitting and crevice attack.
Heat Resistance of Nickel Alloys Alloy C276
Nickel Alloy C276 structural profiles retain good mechanical properties from cryogenic temperatures up to elevated service temperatures typical of the Ni-Cr-Mo family; sustained structural use is generally limited to a few hundred degrees Celsius before long-term aging effects become a concern. Confirm exact service limits against the governing standard and application before specifying.
