Definition of Hastelloy Alloys
Mar 27, 2018

The Halon alloy (Hastelloy alloy) is a general term for the commercial grade of a nickel-based corrosion-resistant alloy produced by the United States. Including nickel-Molybdenum series Hastroy (Hastelloy) B-2, Ni-cr-Mo Series Hastroy (Hastelloy) C-4, etc.

The HA alloy grade includes the following brands:

Hastelloy B-2 ni-mo alloy, in the reductive environment has excellent corrosion resistance Hastelloy B-3 B-2 upgrade version, for any temperature and concentration of hydrochloric acid has excellent corrosion resistance.

Hastelloy C-4 Good thermal stability, 650-1040 degrees Celsius has good toughness and corrosion resistance.

Hastelloy C-22 is better than C-4 and C-276 in oxidizing medium, and has excellent resistance to local corrosion Hastelloy C-276 has good resistance to oxidation and medium reduction corrosion, excellent stress corrosion resistance. Hastelloy C-2000 is the most comprehensive corrosion resistant alloy, and has excellent corrosion resistance in both oxidation and reduction environments.

Hastelloy G-35 G-30 Upgraded products, better corrosion resistance and better thermal stability Hastelloy G-30 High chromium nickel base alloy, in phosphoric acid and other strong oxidizing mixed acid medium outstanding performance.
