If you’re looking for a reliable, corrosion-resistant alloy to produce various industrial components, two of the best options are Hastelloy C2000 and Hastelloy C276. While both alloys offer excellent corrosion resistance, some key differences between them should be taken into account when selecting an alloy for your needs. Let’s take a closer look at the similarities and differences between Hastelloy C2000 and C276.
Hastelloy C2000
Hastelloy C2000 is an austenitic nickel-chromium-molybdenum-tungsten alloy with excellent corrosion resistance across various corrosive media. It has good resistance to stress corrosion cracking and pitting and superior oxidation resistance compared to other alloys of similar composition. It also offers excellent formability and weldability, making it ideal for chemical processing equipment and heat exchanger applications.
Hastelloy C276
Hastelloy C276 is another nickel-chromium-molybdenum alloy with exceptional corrosion resistance in both oxidizing and reducing environments. It has good weldability and formability and can be used in applications such as chemical process equipment and piping systems. However, it does not have the same tungsten content or oxidation resistance level as Hastelloy C2000.
