Hastelloy B-2 – Composition, Properties, and Uses

Hastelloy B-2 – 1. Composition:

The composition of Hastelloy B-2 has been carefully formulated to offer excellent corrosion resistance and mechanical properties. Its key elements include:

  1. Nickel (Ni): This is the primary constituent of the alloy, providing good ductility and corrosion resistance.
  2. Chromium (Cr): Enhances the corrosion resistance of the alloy in oxidizing environments, particularly against sulfuric and hydrochloric acids.
  3. Molybdenum (Mo): Increases the corrosion resistance of the alloy in reducing environments and enhances its resistance to hydrofluoric acid.
  4. Iron (Fe): As a primary alloying element, iron improves the mechanical strength of the alloy.
  5. Cobalt (Co): Enhances the corrosion resistance and high-temperature performance of the alloy by improving its solid solution strengthening effect.
  6. Tungsten (W): Further improves the corrosion resistance of the alloy, especially in oxygen- and sulfur-containing corrosive media.
  7. Minor elements such as Carbon (C), Silicon (Si), and Manganese (Mn): These elements are primarily used to adjust the mechanical properties and processability of the alloy.
