HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. It resists the formation of grain boundary precipitates in the weld-heat affected zone making it suitable for use in the as-welded condition. C-22 has outstanding resistance to both reducing and oxidizing media and because of its resistibility can be used where "upset" conditions are likely to occur. It is proven to possess excellent weldability and high corrosion resistance as consumable filler wires and electrodes. The alloy has proven results as a filler wire in many applications. As filler wire use when other corrosion resistant wires have failed.
C-22 can easily be cold-worked because of its ductility and cold-forming is the preferred method of forming. More energy is required because the alloy is generally stiffer than austenitic stainless steels. 0.28" thick sheet in the heat-treated at 2050°F, rapid quenched condition, has an average olsen cup depth of 0.49".

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 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 serves many different applications in these industry categories:
