About Hastelloy C22 Fittings
Hastelloy C22 fittings are made from a nickel-chromium-molybdenum alloy known for their superior corrosion resistance in a variety of harsh environments, including those containing oxidizing acids, reducing acids, chlorides, and other corrosive chemicals. They are commonly used in chemical processing, pollution control, and other industries where corrosion resistance and high-temperature performance are critical.
