Hastelloy C22 vs C276 vs B2 Tubes
Hastelloy C22 Tube is highly resistant to oxidizing and reducing agents, making it ideal for chemical plants, marine environments, and pollution control systems. Hastelloy C276 Tube is well-known for its superior resistance to pitting, crevice corrosion, and stress cracking, making it an excellent choice in the harsh chemical processing and pulp industries. Hastelloy B2 Tube, on the other hand, is highly resistant to hydrochloric acid and other strong reducing environments, but less effective in oxidizing conditions. The specific chemicals and conditions in your application will determine which alloy to use.
