ʻO Hastelloy alloy C22, ka mea i kapa ʻia ʻo alloy C22, he ʻano multifunctional austenitic Ni-Cr-Mo Tungsten alloy, ʻoi aku ka ikaika o ke kūʻē ʻana i ka lua, crevice corrosion a me stress corrosion cracking.Hāʻawi ka mea kiʻekiʻe o ka chromium i ke kūpaʻa oxidation maikaʻi i ka waena, ʻoiai ʻo ka molybdenum a me ka tungsten content he hoʻomanawanui maikaʻi i ka mea hoʻohaʻahaʻa.
Ua loaʻa iā Hastelloy C-22 ke kinoea acyl antioxidant, ka wai, ka formic a me ka acetic acid, ka ferric chloride a me ka copper chloride, ka wai kai, ka brine a me nā mea hoʻonā i hui ʻia a i ʻole nā mea hoʻonā kemika.
Hāʻawi kēia nickel alloy i ke kūpaʻa maikaʻi loa i nā kaiapuni kahi e ʻike ʻia ai nā kūlana hoʻemi a me ka oxidation i ke kaʻina hana.
Kūleʻa kēia nickel alloy i ka hoʻokumu ʻana i ka palena o ka palaoa i loko o ka wahi wela o ka welding a no laila kūpono ia no ka hapa nui o nā noi kaʻina hana kemika ma lalo o nā kūlana kuʻi.
ʻAʻole pono e hoʻohana ʻia ʻo Hastelloy C-22 i nā mahana i ʻoi aku ka kiʻekiʻe ma mua o 12509F ma muli o ka hoʻokumu ʻana o nā pae ʻino i ʻoi aku ka kiʻekiʻe ma mua o kēia mahana.
