Application
Hastelloy are widely used in various industries where resistance to aggressive chemical environments is required.
Hastelloy are available in different grades, each with its own specific chemical composition and properties. Some common grades of Hastelloy plates include:
Hastelloy C276: This grade contains a high percentage of nickel (around 57%) along with significant amounts of chromium (up to 16%), molybdenum (up to 17%), and small amounts of tungsten and iron. Hastelloy C276 plates offer excellent resistance to corrosion in a wide range of aggressive media, including sulfuric acid, hydrochloric acid, and chloride solutions.
Hastelloy C22: Hastelloy C22 plates possess a similar nickel content as Hastelloy C276, but with higher chromium (20-22%) and lower molybdenum (12.5-14.5%) levels. This composition provides superior resistance to oxidizing and non-oxidizing corrosive environments, such as wet chlorine gas, nitric acid, and acetic acid.
Hastelloy B-3: Hastelloy B-3 plates are primarily composed of nickel (65-70%), molybdenum (26-30%), and a small amount of iron. This grade offers excellent resistance to hydrochloric acid at all concentrations and temperatures, making it suitable for chemical processing applications.
