Hastelloy Alloys

Hastelloy is a family of corrosion-resistant metal alloys primarily composed of nickel, with varying amounts of molybdenum, iron, cobalt, and chromium. Known for their exceptional resistance to strong oxidizers and reducing agents, Hastelloy alloys are ideal for harsh chemical environments. Commonly used in chemical processing, power plants, marine applications, and aerospace industries, they provide long-term durability and stability.

  • Outstanding resistance to strong oxidizing and reducing chemicals
  • Excellent performance in high-temperature and high-stress conditions
  • Highly resistant to pitting, stress corrosion cracking, and crevice corrosion
  • Suitable for use in reactors, heat exchangers, and pressure vessels

Exceptional Corrosion Resistance

Hastelloy alloys resist highly aggressive chemicals, including hydrochloric acid, sulfuric acid, and wet chlorine—ideal for chemical reactors and scrubbers.

Protection
High Temperature Stability

Hastelloy maintains mechanical and chemical stability even in extreme heat, making it reliable for furnaces, heat exchangers, and high-temperature vessels.

Thermal Strength
Excellent Fabricability

Easily formed, welded, and machined, Hastelloy is ideal for custom chemical equipment, piping, and flanges requiring complex shapes or tight tolerances.

Flexibility
Resistant to Pitting and Cracking

With superior resistance to localized corrosion forms such as pitting, stress corrosion cracking, and crevice attack, Hastelloy ensures longevity in aggressive environments.
