High Resistance to Hydrochloric Acid, Sulfuric Acid, Pitting, and Crevice Corrosion
Hastelloy HYBRID-BC1 (UNS N10362) alloy possesses much higher resistance to hydrochloric and sulfuric acids than the nickel-chromium-molybdenum (C-type) alloys, and can tolerate the presence of oxidizing species. The alloy also exhibits extremely high resistance to pitting and crevice corrosion.
Hastelloy HYBRID-BC1 Applications
Hastelloy HYBRID-BC1 alloy is suitable for the following applications in the chemical processing, pharmaceutical, agricultural, food, petrochemical, and power industries
- Reaction vessels
- Heat exchangers
- Valves
- Pumps
- Piping
- Storage tanks
The alloy is suitable for use at temperatures up to approximately 427°C (800°F). HYBRID-BC1 alloy excels in reducing acids and acid mixtures (with or without halides) open to oxygen and other oxidizing residuals/contaminants.
