What is corrosion rate & pressure rating of hastelloy C276 flange?

Hastelloy C276 is a nickel-molybdenum-chromium alloy with excellent corrosion resistance in severe environments. It is widely used in applications such as chemical processing, petrochemical, and marine industries due to its outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking.

Corrosion rate: The corrosion rate of hastelloy c276 flanges depends on the specific environment and operating conditions. In general, Hastelloy C276 demonstrates very low corrosion rates in a wide range of aggressive media. For example, in sulfuric acid, the corrosion rate of Hastelloy C276 is generally less than 5 mpy (mils per year) at concentrations up to 70%, while in hydrochloric acid, the corrosion rate is typically less than 20 mpy at concentrations up to 10%. However, it is essential to consult corrosion data for the specific operating conditions and chemical concentrations to determine the exact corrosion rate of alloy c-276 flanges in a given environment.

Pressure rating: The pressure rating of a hastelloy flanges is determined by several factors, including flange size, class, temperature, and applicable design standards (such as ASME B16.5 or ASME B16.47). Flange class ratings range from 150 to 2500, with higher class ratings corresponding to higher pressure resistance. The pressure rating decreases as the temperature increases. To determine the exact pressure rating of a Hastelloy C276 flange, you should refer to the design standards, flange size, and class for the specific application.
