Hastelloy Alloys – Extreme Corrosion Resistance for Aggressive Chemical Environments
XURUI offers a comprehensive selection of Hastelloy alloy products—including pipes, plates, bars, wires, strips, flanges, fittings, forgings, and customized components—covering all major grades across the C, B, G, and X series.
Hastelloy® is a trademarked family of nickel-based superalloys developed by Haynes International. These alloys are engineered to resist highly aggressive chemical media, such as: Hydrochloric acid, Sulfuric acid, Ferric chloride, Sodium hypochlorite, Acetic & phosphoric acids.
Its superior thermal stability, stress corrosion cracking resistance, and pitting resistance make it ideal for extreme conditions where stainless steel or lower alloys fail.
- C-276 – Most versatile grade for oxidizing/reducing media
- C-22 – Higher resistance to oxidizing agents like nitric acid
- B-2 / B-3 – Excellent in hydrochloric and non-oxidizing acids
- X / G30 / G35 – Niche applications in fertilizer, pickling & heat exchangers

Hastelloy B
Hastelloy B-2 and B-3 alloys are resistant to acid, reducing environments so tend to be selected for piping and valves where Hydrochloric and Sulphuric acids are chemicals that are used in the process plant. The acids can be handled in liquid or gaseous form. In a further advancement, Hybrid Hastelloy BC-1 is a new "Ni-Cr-Mo" alloy with superior resistance to hydrochloric and sulfuric acids, without the drawbacks of the Ni-Mo materials.
Hastelloy C-4
The C-4 alloy has high-temperature stability in the 1200-1900°F (650-1040°C) range as evidenced by good ductility and corrosion resistance. It possesses virtually the same corrosion resistance as alloy C-276.
Hastelloy C-22
C-22 has better overall corrosion resistance to oxidizing corrosives than C-4, C-276 and 625 alloys. This alloy is also considered to be the best choice as a universal weld filler metal to resist corrosion at any weld.
Hastelloy C-276
C-276 is a versatile, corrosion-resistant alloy, which makes it a frequently selected fabrication material in the petrochemical and other industries. All common methods of welding can be used due to the low carbon and silicon content. It has exceptional stress corrosion cracking resistance with high resistance to localized sulfide attack. Its main advantage over Inconel and Incoloy is that Hastelloy is easier to weld.
