Common Hastelloy Alloy Grades

Hastelloy alloys are a group of high-performance nickel-based alloys known for their exceptional resistance to corrosion and chemical attack. These alloys are specifically designed to perform in extremely aggressive environments where conventional stainless steels or other materials may fail.

Different Hastelloy grades are designed for specific corrosion conditions and temperature ranges

Series B: Nickel-Molybdenum Alloys (Ni-Mo)

Designed for non-oxidizing acidic media such as hydrochloric and sulfuric acids, offering exceptional resistance to reducing corrosion.

  • ‌Hastelloy B-2‌ (UNS N10665)
    Ultra-low carbon and silicon content minimizes precipitation in the heat-affected zone during welding, ensuring superior post-weld corrosion resistance; performs excellently across all concentrations and temperatures of hydrochloric acid.
  • ‌Hastelloy B-3‌ (UNS N10675)
    An upgraded version of B-2 with enhanced resistance to Ni₃Mo phase precipitation, improved hot workability, and broader applicability in hydrochloric acid environments of any concentration.

‌Series C: Nickel-Chromium-Molybdenum Alloys (Ni-Cr-Mo)

Combines oxidation and reduction resistance, making it the most widely used family of Hastelloy alloys.

  • ‌Hastelloy C-4‌ (UNS N06455)
    Maintains excellent toughness and corrosion resistance in the temperature range of 650–1040°C; ideal for high-temperature applications requiring thermal stability.
  • ‌Hastelloy C-276‌ (UNS N10276)
    Tungsten-containing Ni-Cr-Mo alloy with outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking; one of the few materials capable of withstanding wet chlorine, hypochlorite, and chlorine dioxide solutions; extensively used in flue gas desulfurization and chemical reactors.
  • ‌Hastelloy C-22‌ (UNS N06022)
    Higher chromium content (~20%) enhances oxidation resistance compared to C-276; superior performance in chloride-rich, nitrate-containing, and mixed oxidizing environments; commonly applied in pharmaceutical equipment and desulfurization systems.
  • ‌Hastelloy C-2000‌ (UNS N06200)
    Incorporates copper to significantly improve resistance to sulfuric and hydrofluoric acids in reducing media; represents the most comprehensive corrosion-resistant alloy in the Hastelloy family.

‌Series G: Nickel-Chromium-Molybdenum-Copper Alloys (Ni-Cr-Mo-Cu)

Engineered for complex, highly oxidizing environments such as phosphoric acid and mixed nitric/hydrochloric acid systems.

  • ‌Hastelloy G-30‌ (UNS N08030)
    High chromium content delivers exceptional resistance to commercial-grade phosphoric acid and other strong oxidizing acid mixtures.
  • ‌Hastelloy G-35‌ (UNS N06985)
    An advanced variant of G-30 with improved corrosion resistance and thermal stability; suitable for heat exchangers in phosphoric acid production and flue gas scrubbers.

‌Series X: Nickel-Chromium-Iron-Molybdenum Alloys (Ni-Cr-Fe-Mo) ‌

Combines high strength, oxidation resistance, and ease of fabrication for elevated-temperature components.

  • ‌Hastelloy X‌ (UNS N06002)
    Retains ductility and structural integrity at temperatures up to 1200°C; widely used in aircraft combustion chambers, rocket nozzles, and gas turbine afterburners.

‌Other Significant Grades‌

  • ‌Hastelloy 230‌ (UNS N06230)
    Exhibits exceptional high-temperature oxidation resistance and carburization resistance up to 1100°C; ideal for furnace components and thermal processing equipment.
  • ‌Hastelloy S‌ (UNS N06635)
    Features low thermal expansion and excellent thermal stability; commonly employed in gas turbine seals and high-temperature structural components.

Industries That Use Hastelloy Alloys

Because of their outstanding resistance to acids, oxidation, and high temperatures, Hastelloy alloys are widely used in industries such as chemical processing, oil & gas, aerospace, nuclear engineering, and marine equipment.
