What is the difference between Hastelloy C276 and hastelloy c-22?
Hastelloy C276 can withstand temperatures up to 1900°F (1037°C), while Hastelloy C22 can withstand temperatures up to 1250°F (676°C). The increased thermal stability and resistance to grain boundary precipitation make Hastelloy C276 a popular choice for applications in high temperature environments.

What is Hastelloy C22 used for?
C-22 is suitable for highly corrosive media with high chlorides and high temperatures, such as buffer solutions, active pharmaceutical ingredients (APIs), fabric softeners, cleaning products, and fish, soy and chili sauces.

What is Hastelloy C276 used for?
Hastelloy C276 has become a trusted material for flange applications due to its excellent corrosion resistance, heat resistance and stress resistance. It is widely used in various industries, including chemical processing plants, petrochemicals, power generation, marine environments, etc.

What does C276 mean?
Hastelloy C276 is a nickel-chromium-molybdenum wrought alloy that is considered the most widely used corrosion-resistant alloy available.
