Have you heard of hastelloy? Consider this.

According to Corrosionpedia:

Hastealloy is a term that refers to a group of 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.

Corrosionpedia Explains Hastelloy

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:

  1. Molybdenum (Mo) – 30%
  2. Chromium (Cr) – 23%
  3. Iron (Fe) – 29%

In addition to corrosion resistance, hastealloys provide the following benefits when used in metal applications:

  • Exceptional resistance to strong oxidizing solutions
  • Strong durability in reducing environments
  • A low carbon content that provides minimization of grain-boundary carbide precipitation
