Nickel-Chromium-Molybdenum Alloy
Hastelloy C-22
Hastelloy C-22 is a versatile nickel-chromium-molybdenum-tungsten alloy with superior corrosion resistance compared to other nickel-based alloys, including Hastelloy C-276, C4, and Inconel 625.
It offers exceptional resistance to oxidizing aqueous environments, including wet chlorine, nitrate solutions containing chlorides, and mixed oxidizing acids. Its ability to withstand alternating reducing and oxidizing process streams makes it an ideal choice for demanding industrial applications.
