| Hastelloy Family of Corrosion-Resistant Alloys | ||
|---|---|---|
| Hastelloy B-3 alloy | Same excellent resistance to hydrochloric acid and other strongly reducing chemicals as B-2 alloy, but with significantly better thermal stability, fabricability and stress corrosion cracking resistance. | |
| Hastelloy HYBRID- BC1 alloy | A new Ni-Cr-Mo alloy with superior resistance to hydrochloric and sulfuric acids, without the drawbacks of the Ni-Mo and Zr materials. Its resistance to these key chemicals is much greater than that of the popular Ni-Cr-Mo (C-type) alloys, yet it shares with them the outstanding resistance to pitting and crevice attack in chloride salt solutions, and even withstands high levels of oxidizing impurities that the Ni-Mo alloys cannot cope with. | |
| Hastelloy C-4 alloy | High-temperature stability in the 1200-1900°F (650-1040°C) range as evidenced by good ductility and corrosion resistance. Virtually the same corrosion resistance as alloy C-276. | |
| Hastelloy C-22 alloy | Better overall corrosion resistance in oxidizing corrosives than C-4, C-276 and 625 alloys. Outstanding resistance to localized corrosion and excellent resistance to stress corrosion cracking. Best alloy to use as universal weld filler metal to resist corrosion of weldments. | |
| Hastelloy C-22HS alloy | This alloy was designed to exhibit corrosion resistance comparable to other C-type alloys, but which can be heat treated to obtain approximately double the yield strength. | |
| Hastelloy C-276 alloy | Versatile, corrosion resistant alloy. Very good resistance to reducing, and mildly oxidizing corrosives. Excellent stress corrosion cracking resistance with very good resistance to localized attack. | |
| Hastelloy C-2000 alloy | Most versatile, corrosion resistant alloy with excellent resistance to uniform corrosion in oxidizing or reducing environments. Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. | |
Hastelloy is very well suited to many industrial processes. The following are some of the environments in which Hastelloy is fully resistant*.

*Please Note: Final selection of material must be based on actual evaluation of the metal in the corrosive medium under study and is the responsibility of the end user. Temperature and concentration play an important factor in corrosion resistance.
