What Is Hastelloy C22 Tube?
Hastelloy C22 Tube is a nickel-chromium-molybdenum alloy with excellent resistance to pitting, crevice corrosion and stress corrosion cracking. It has outstanding resistance to sulfuric and hydrochloric acids and other non-oxidizing media. C-22 Hastelloy Tube is a combination of chromium, molybdenum and tungsten which provides better corrosion resistance than other nickel-based alloys.
C-22 Hastelloy Tube is available in various forms, such as round tubes, square tubes, rectangular tubes, hexagonal tubes, and coiled tubing. It is available in sizes ranging from 1/16" to 6" in diameter. The price of C-22 Hastelloy Tube depends on the size and quantity. Generally, it is more expensive than other types of alloy tubes.
