Hastelloy C22yog cov nickel alloy thiab muaj qhov tshwj xeeb corrosion kuj hauv oxidizing thiab txo qhov chaw, nrog rau cov xwm txheej hnyav uas muaj cov tshuaj chlorides, acids, thiab kub siab. Cov ntaub ntawv no qhia txog cov khoom siv, cov qauv, thiab cov ntsiab lus haum raws li ASME B366.
Hastelloy C22 Cov khoom siv tshuaj lom neeg muaj pes tsawg leeg
Hastelloy C22 yog austenitic nickel alloy thiab muaj kev tiv thaiv zoo tshaj rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg piv rau C276. Nws nthuav tawm cov kev ua tau zoo hauv oxidizing thiab txo qhov chaw, suav nrog cov chlorine ntub dej, formic acid, acetic acid, ferric chloride, thiab dej hiav txwv.
