ASME SB622 C22 UNS NO6022 Hastelloy Steel Seamless Tube
UNS N06022 is a nickel based high-temperature alloy composed of elements such as nickel， molybdenum， cobalt， and tungsten. The nickel content is approximately 60%. It is a universal Ni Cr Mo W alloy with better overall corrosion resistance than other existing Ni Cr Mo alloys， including Hastelloy C-276， C4 alloy， and 625 alloy. UNS N06022 has good resistance to pitting， Crevice corrosion and stress corrosion cracking. It has excellent antioxidant capacity in aqueous media， including wet chlorine， nitric acid， or mixed acids containing chloride ions. At the same time， UNS N06022 alloy also has ideal resistance to the reduction and oxidation environments encountered during the process. With this multifunctional performance， it can be used in some troublesome environments or factories for various production purposes.
UNS N06022 has abnormal resistance to various chemical environments， including strong oxidizing substances， such as ferric chloride， Copper(II) chloride， chlorine and Thermal pollution solutions. Liquids (organic and inorganic)， formic acid， acetic acid， cusuan anhydride， seawater， and salt solutions. Inconel 622 alloy has the ability to resist grain boundary precipitation in the heat affected zone (HAZ)， and is suitable for various Chemical process in the welding state.

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). |
