- 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 alloys 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 re-ducing environments. Excellent resistance to stress corrosion cracking and superior resistance to localized corrosion as compared to C-276 alloy. |
| HASTELLOY® G-30® alloy |
Many advantages over other metallic and non-metallic materials in handling phosphoric acid, sulfuric acid, nitric acid, fluoride environments and oxidizing acid mixtures. |
| HASTELLOY® G-35® alloy |
Excellent resistance to corrosion in highly oxidizing media and acidic chloride environments. |
| HASTELLOY® N alloy |
Good resistance to aging and embrittlement and good fabricability. It has excellent resistance to hot fluoride salts in the temperature range of 1300°F to 1600°F (705°C-870°C). |

- Hastelloy Alloys Typical Physical Properties Available:
BAR * FOIL * SHEET * PLATE * TUBING * WIRE
- Hastelloy Alloys Typical Applications:
a) Used heavily within the chemical process industries to protect equipment from aqueous corrodents.
b) The primary function of the Hastelloy super alloys is that of effective survival under high-temperature, high-stress service in a moderately to severely corrosive, and/or erosion prone environment where more common and less expensive iron-based alloys would fail, including the pressure vessels of some nuclear reactors, chemical reactors, and pipes and valves in chemical industry.
