Hastelloy Alloy Summary:

Hastelloy alloy is corrosion resistant metal mixtures that are based on nickel. Hastealloys have a unique combination of properties that provide them with significantly stronger corrosion resistance capabilities compared to traditional alloys.The two main hastealloys are nickel-molybdenum (Ni-Mo) and nickel-chromium (Ni-Cr). The key elements that are often combined with nickel and their corresponding percentage concentrations are as follows:
Molybdenum (Mo) - 30%
Chromium (Cr) - 23%
Iron (Fe) - 29%
The corrosion-resistant Hastelloy alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of geothermal, solar energy, oil and gas and pharmaceutical. The benefits of Hastelloy process equipment include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication.
