A Nickel-Chromium-Molybdenum alloy with better overall resistance and versatility than any other NiCrMo available. It has excellent resistance to localised corrosion and to a variety of mixed industrial chemicals. Hastelloy C22 is used in severely corrosive media involving high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and condiments such as soy and chili sauce. Like other nickel alloys, Hastelloy C22 is extremely ductile, exhibits exceptional weldability, and can easily be fabricated into industrial components.
Hastelloy C22 is also known as Nicrofer 5621, Superimphy C22, and Inconel 622.
Diameter: 0.1 - 40mm
Shape: round, square, flat, special shaped
Hastelloy C22 offers the following key features:
Better overall corrosion resistance than Hastelloy C-4 & C-276 and Inconel 625.
Outstanding resistance to pitting, crevice corrosion and stress corrosion cracking.
Hastelloy C22 is known to be suitable for the following applications:
Chlorination systems
Nuclear fuel reprocessing
Pickling systems
