Differences between Hastelloy C4 and Hastelloy C22:
chemical composition:
The chemical composition of Hastelloy C4 is 65% nickel, 16% chromium, 16% molybdenum and 2% iron. Hastelloy C22, on the other hand, has a chemical composition of 56% nickel, 22% chromium, 13% molybdenum, and 3% tungsten, with small amounts of iron, cobalt, and manganese. This compositional difference determines their resistance to various corrosive media, including sulfuric acid, hydrochloric acid and acetic acid. Hastelloy C22 is more resistant to these media than Hastelloy C4 due to the addition of tungsten.
Temperature resistance:
Hastelloy C4 has an upper temperature limit of 1900°F (1038°C), while Hastelloy C22 can withstand up to 2200°F (1204°C). Therefore, if you have an industrial application that requires exposure to extreme temperatures, Hastelloy C22 is a better choice.
Weldability:
Hastelloy C4 is easier to weld than Hastelloy C22 due to its lower carbon content. Welding Hastelloy C22 requires preheating and post-weld heat treatment to prevent stress corrosion cracking. Therefore, if you are dealing with a highly welding-intensive application, the Hastelloy C4 may be your first choice.
price:
Hastelloy C22 is more expensive than Hastelloy C4 due to its higher corrosion resistance, higher temperature limits and processing requirements. Therefore, if cost is a driving factor, the Hastelloy C4 may be a more economical solution for your industrial needs.
in conclusion:
Hastelloy C4 and Hastelloy C22 are excellent alloys for industrial applications, depending on the corrosive environment and temperature requirements of the medium. However, their properties differ in terms of chemical composition, temperature resistance, solderability, and price. Hastelloy C22 stands out for its higher resistance to corrosive media and temperature limits, while Hastelloy C4 is the better choice for welding-intensive applications and cost-effective solutions.
