Applications & Benefits
Why this grade
Hastelloy B3 resists the same reducing acids as B2, but its composition was reformulated to suppress the intermetallic precipitation that embrittles B2 in the 550–900°C range. The result is far better thermal stability, so welded and formed sections keep their ductility in service. Specify B3 wherever B2 chemistry is wanted in new fabrication.
- Chemical reactors and heat exchangers processing oxidizing and reducing acids
- Oil & gas components exposed to highly aggressive sour environments
- Marine desalination and seawater cooling systems
- Pharmaceutical process vessels and sterilization equipment
- Power generation heat exchangers and emission control equipment
