Comprehensive range of high-performance Hastelloy flanges engineered for the most demanding industrial applications
Our Hastelloy Flange Products
Premium alloys designed for superior corrosion resistance
Hastelloy C276 Flanges
The most widely used Hastelloy alloy, offering exceptional corrosion resistance in oxidizing and reducing environments. Ideal for chemical processing, pollution control, and pulp production.
Key Features:
- Excellent resistance to pitting and crevice corrosion
- Superior performance in mixed acid environments
- High resistance to chloride-induced stress corrosion cracking
- Temperature range: -196°C to 650°C
Hastelloy C22 Flanges
Advanced alloy with enhanced resistance to oxidizing aqueous media. Preferred for extreme corrosive environments where C276 may not be sufficient.
Key Features:
- Outstanding resistance to oxidizing acids
- Excellent resistance to localized corrosion
- Superior performance in chlorine-containing environments
- Wide range of chemical process applications
Hastelloy B-3 Flanges
Specialized alloy designed for hydrochloric acid and other reducing environments. Offers superior thermal stability compared to earlier B-series alloys.
Key Features:
- Excellent resistance to hydrochloric acid
- Outstanding thermal stability
- Resistance to sulfuric acid and other reducing acids
- Minimal carbide precipitation during welding
