Hastelloy Products Overview

Hastelloy is a family of corrosion-resistant metal alloys primarily based on nickel. They are known for their excellent resistance to a wide range of harsh environments, such as high temperatures and acidic or corrosive substances. Hastelloy is used in chemical processing, aerospace, and energy sectors due to its outstanding mechanical and chemical properties.

Properties of Hastelloy
  • Exceptional Corrosion Resistance: Resistant to a wide range of acids, including hydrochloric acid, sulfuric acid, and phosphoric acid.
  • High-Temperature Stability: Withstands high temperatures without losing its strength.
  • High Strength: Provides excellent tensile and yield strength.
  • Durability: Ideal for applications involving aggressive chemicals and extreme conditions.
  • Excellent Weldability: Hastelloy alloys are easily welded and fabricated into complex shapes.
Applications of Hastelloy Products
  • Chemical Processing: Used in reactors, heat exchangers, and other equipment exposed to corrosive environments.
  • Aerospace: Used in aircraft and spacecraft components that must withstand extreme conditions.
  • Energy Industry: Applied in nuclear reactors, power plants, and geothermal plants.
  • Pharmaceutical Industry: Used in processing equipment for drug manufacturing and sterilization equipment.
  • Marine Industry: Suitable for marine environments due to its resistance to seawater corrosion.
