Hastelloy Hybird-BC1 (UNS N10362 / W.Nr. 2.4708)
Hastelloy Hybird-BC1 (UNS N10362 / W.Nr. 2.4708) 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 re- sistance to pitting and crevice corrosion.

- Immune to chloride ion stress corrosion
- Maintains high strength at elevated temperatures
- Resistant to sea water, in both flowing and stagnant condition
- Heat resistant
Applications
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.
