Hastelloy C-276 technical parameters
| Hastelloy C-276(UNS N10276) | |||||||||
| Summary | Nickel molybdenum chromium alloy, with tungsten, has excellent corrosion resistance to a variety of harsh environments. The high molybdenum content makes the alloy particularly resistant to pitting and seams.The low carbon content minimizes the carbon precipitation of the alloy during the welding process, thus maintaining the corrosion resistance in the welded structure. For pollution control, chemical, pulp and paper, waste disposal. | ||||||||

Microstructure
C-276 is a basic strengthened face-centered cubic crystal lattice alloy of solid solution type
Characters
Hastellay C-276 alloy, containing tungsten and very low content of carbon and silicon, has the following characteristics:
1.In the oxidation and reduction state, it has excellent corrosion resistance to most corrosion media;
2.Excellent point corrosion resistance, crack corrosion and stress corrosion cracking performance.
Corrosion Resistance
Hastelay C-276 alloy is suitable for various chemical process industries containing oxidation and reducing media. The high molybdenum and chromium content enables the alloy to resist the erosion of chloride ions, and the tungsten element also further improves its corrosion resistance. C-276 is one of the few materials that can withstand corrosion of wet chlorine gas, hypochlorite and chlorine dioxide solution, this alloy has significant resistance to high concentration of chloride solution corrosive. (as ferric chloride and copper chloride).
