Composition and Applications about Hastelloy C276 Flanges

Hastelloy C276 is a nickel-molybdenum-chromium alloy that also contains small amounts of tungsten, iron, and cobalt. The following is the typical composition of Hastelloy C276:

• Nickel (Ni): 55%

• Molybdenum (Mo): 16%

• Chromium (Cr): 16%

• Tungsten (W): 4%

• Iron (Fe): 5%

• Cobalt (Co): 2.5%

• Manganese (Mn): 1%

• Vanadium (V): 0.2%

• Silicon (Si): 0.08%

• Carbon (C): 0.01%

Hastelloy C276 has a high nickel content, which provides excellent resistance to corrosion in a wide range of environments, including strong oxidizers, reducing acids, and chlorides. The molybdenum content provides additional resistance to pitting and crevice corrosion, while the chromium content enhances the material's resistance to oxidizing environments. The tungsten content also contributes to the material's strength and corrosion resistance in aggressive media.

Overall, the combination of these elements gives Hastelloy C276 its excellent corrosion resistance, high-temperature strength, and good fabricability, making it suitable for a wide range of applications in various industries, including chemical processing, oil and gas, and pulp and paper.
