Hastelloy alloy C22, inozivikanwawo se alloy C22, imhando ye multifunctional austenitic Ni-Cr-Mo Tungsten alloy, ine yakasimba kuramba pitting, crevice corrosion uye stress corrosion kuparuka.Iyo yakakwira chromium yemukati inopa yakanaka oxidation kuramba kune yepakati, nepo molybdenum uye tungsten zvemukati zvine kushivirira kwakanaka kune inoderedza svikiro.
Hastelloy C-22 ine antioxidant acyl gasi, hunyoro, formic uye acetic acid, ferric chloride uye mhangura chloride, mvura yegungwa, brine uye akawanda akasanganiswa kana akasvibiswa organic uye inorganic makemikari mhinduro.
Iyi nickel alloy inopawo kwakaringana kuramba munzvimbo umo kudzikiswa uye oxidation mamiriro anosangana panguva yekuita.
Iyi nickel alloy inoshingirira kuumbwa kwemuganho wezviyo inonaya munzvimbo inopisa yakakanganiswa yewelding uye saka yakakodzera kune mazhinji kemikari process application pasi pemamiriro ewelding.
Hastelloy C-22 haifanirwe kushandiswa patembiricha inodarika 12509F nekuda kwekuumbwa kwezvikamu zvinokuvadza zvakakwirira kudarika tembiricha iyi.

•Nickel-Chromium-Molybdenum-Tungsten alloy ine zvirinani zvakazara corrosion resistance kana zvichienzaniswa nemamwe maNi-Cr-Mo alloys, akadai seHastelloy C-276, C-4 uye alloy 625.
•Kuramba kwakanaka kugomba corrosion, crevice corrosion uye stress corrosion kuparuka.
•Yakanakisa kuramba kune oxidizing aqueous media inosanganisira wet chlorine uye misanganiswa ine nitric acid kana oxidizing acid ine chlorine ion.
•Kupa kwakaringana kuramba kune nharaunda uko kudzikisira uye oxidizing mamiriro anosangana mukuita nzizi.
•Inogona kushandiswa mune imwe nzvimbo yemusoro nharaunda kune yepasirese chivakwa, kana kushandiswa mumhando dzakasiyana dzekugadzira fekitori.
•Kupokana kwakasarudzika kune dzakasiyana siyana dzemakemikari process nharaunda dzinosanganisira yakasimba oxidizer senge ferric acids, acetic anhydride, uye mvura yegungwa uye brine mhinduro.
•Inoramba kuumbwa kwezviyo-muganho wemvura munzvimbo yeweld-yakakanganiswa nekupisa, ichipa yakanakisa se-welded mamiriro ekugadzirisa mashandisirwo mumaindasitiri ane makemikari.
Inoshandiswa zvakanyanya mumunda wemakemikari uye petrochemical, sekushandiswa mune organic components ine chloride uye catalytic systems.Ichi chinyorwa chinonyanya kukodzera kupisa kwakanyanya,inorganic acid uye organic acid (senge formic acid uye acetic acid) yakasanganiswa netsvina,gungwa. mvura corrosion environments.Inogona kushandiswa kugadzira zvinotevera midziyo kana zvikamu:
