C-276 alloy has a wide range of chemical compatibility and can perform well in a variety of corrosive environments, especially in the presence of chlorides, sulfuric acid and other highly corrosive chemicals.
The main chemical components of C-276 alloy include:
Nickel (Ni): about 65%
Chromium (Cr): about 15%
Molybdenum (Mo): about 4.5%
Iron (Fe): about 6%
Tungsten (W): a small amount
Other elements (such as cobalt, carbon, etc.)
2. Corrosion resistance
Alloy C-276 has excellent corrosion resistance, which is specifically manifested in the following aspects:
It exhibits strong corrosion resistance in a variety of acidic media (such as sulfuric acid, hydrochloric acid, phosphoric acid and nitric acid).
It exhibits excellent resistance to stress corrosion cracking in chloride-containing environments, such as seawater or sodium hypochlorite, and its probability of stress corrosion cracking is extremely low.
It also exhibits a low corrosion tendency in oxidizing environments, such as boiling concentrated nitric acid.
3. Mechanical properties and elongation
Alloy C-276 not only has excellent corrosion resistance, but also outstanding mechanical properties, especially high elongation. Elongation is usually used to measure the plastic deformation ability of materials in tensile tests, which is crucial to their processing and use performance. Specifically:
Under high temperature environment, the elongation of Alloy C-276 is slightly reduced, but can still be maintained above 30%. Experimental data show that at 600℃, its elongation can still reach 32%.
The elongation performance under tensile stress is also good. Under a tensile load of 100MPa, the elongation of the alloy is about 45%.
