Chemical Composition Comparison of Hastelloy Alloys:

Alloy Ni (%) Cr (%) Mo (%) Fe (%) Co (%) W (%) C (%) Mn (%) Si (%) P (%) S (%) Cu (%)
C-276 Bal 14.5-16.5 15-17 4-7 2.5-3.5 3-4.5 0.01 max 1.0 max 0.08 max 0.04 max 0.03 max 0.5 max
B-2 Bal 1.0 max 26.0-30.0 2.0 max 1.0 max – 0.02 max 1.0 max 0.1 max 0.04 max 0.03 max 0.2 max
B-3 Bal 1.0 max 28.5-34.0 3.0 max 1.0 max – 0.01 max 3.0 max 0.1 max 0.04 max 0.03 max 0.2 max
C-22 Bal 20.0-22.5 12.5-14.5 2.0-6.0 2.5 max 2.5-3.5 0.01 max 0.50 max 0.08 max 0.02 max 0.02 max 0.50 max

 

Key Elements:

  • Nickel (Ni): Provides corrosion resistance.
  • Chromium (Cr): Enhances resistance to oxidizing environments.
  • Molybdenum (Mo): Imparts resistance to reducing environments and pitting corrosion.
  • Iron (Fe): Can affect corrosion resistance and mechanical properties.
  • Cobalt (Co): Enhances high-temperature strength.
  • Tungsten (W): Improves resistance to localized corrosion.
  • Carbon (C): Controls carbide precipitation.
  • Manganese (Mn), Silicon (Si), Phosphorus (P), Sulfur (S): Trace elements influencing material properties.
  • Copper (Cu): Enhances resistance to sulfuric acid and other reducing acids.

 

Summary:

  • Hastelloy C-276: Well-balanced with good corrosion resistance in a wide range of environments.
  • Hastelloy B-2: Excellent resistance to hydrochloric acid, sulfuric acid, and other strong reducing chemicals.
  • Hastelloy B-3: Improved thermal stability and resistance to stress corrosion cracking.
  • Hastelloy C-22: Outstanding resistance to both oxidizing and reducing environments, including mixed acids.

 

These alloys are chosen based on specific application requirements, balancing factors such as corrosion resistance, mechanical strength, and environmental conditions.
