Hastelloy is a premier family of corrosion-resistant superalloys designed to survive where other metals fail. Engineered with high molybdenum and chromium content, these alloys offer supreme resistance to a wide range of severe chemical processing environments, including highly oxidizing and reducing acids.
Hastelloy alloys are the industry standard for chemical processing due to their versatility. Whether facing wet chlorine gas, sulfuric acid, or hydrochloric acid, the metallurgical structure remains stable, preventing localized attack and catastrophic failure.
