What is the difference between hastelloy c276 and Inconel 625?

Both Inconel 625 and Hastelloy C-276 are nickel-chromium-molybdenum based alloys. They both have excellent corrosion resistance and good strength. Comparing the two alloys, Inconel 625 has a higher chromium content, while Hastelloy C-276 has a higher molybdenum content.

Hastelloy C276 has become a trusted material for flange applications due to its excellent corrosion resistance, heat resistance and stress resistance. It is widely used in various industries, including chemical processing plants, petrochemicals, power generation, marine environments, etc.

Inconel 625 (UNS N06625) is a nickel-chromium-molybdenum alloy that has excellent corrosion resistance in a variety of corrosive media, especially pitting and crevice corrosion. However, in corrosive environments, Inconel 625 will corrode like other metals.

The difference is that Monel 400 does not have very effective solid solution strengthening elements, and its strength is relatively limited; Inconel 625 adds two very effective solid solution strengthening elements to obtain higher strength, namely molybdenum and niobium.
