Product Details

Product Description:

The C276 seamless tubes are mainly made of a nickel-based corrosion-resistant alloy, Hastelloy C-276, which is considered to be a versatile corrosion-resistant alloy. It has excellent corrosion resistance to most corrosive media, especially excellent pitting resistance in both oxidizing and reducing states. The higher molybdenum and chromium content makes the alloy resistant to chloride ion corrosion and the tungsten element further enhances its corrosion resistance. At the same time, as one of the few materials that can be applied to hot concentrated sulfuric acid, it is suitable for various concentrations of sulfuric acid solution.
