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:
- Molybdenum (Mo) – 30%
- Chromium (Cr) – 23%
- 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
