What is Hastelloy?

Hastelloy is a family of nickel-based superalloys developed by Haynes International for superior corrosion resistance in the most aggressive chemical environments. These high-performance alloys combine nickel, molybdenum, and chromium to provide exceptional resistance to acids, chlorides, and high-temperature oxidation.

Chemical Resistance

Outstanding performance in acids, chlorides, and wet corrosion

Stress Corrosion Resistance

Excellent resistance to chloride stress corrosion cracking

Industry Standard

Trusted by chemical processing and petrochemical industries

Chemical Composition

Hastelloy alloys typically contain:

• Nickel: 50-70% (base element)
• Molybdenum: 15-28% (corrosion resistance)
• Chromium: 13-22% (oxidation resistance)
• Iron: 3-18% (structural properties)
• Tungsten: 0-4% (strength enhancement)
• Other elements: Co, Mn, V, C (specific properties)
