Vim li cas thiaj xaiv Hastelloy C276 rau kev ua tshuaj?
Hastelloy C276 (UNS N10276) yog siv rau hauv kev ua tshuaj lom neeg uas cov hlau tsis muaj hlau yuav raug txwv los ntawm cov kua qaub, chlorides lossis cov txheej txheem sib xyaw. Nws muaj pes tsawg leeg muaj li 16% Mo, 16% Cr thiab 4% W, nrog C Tsawg dua los yog sib npaug rau 0.01% thiab Si Less dua los yog sib npaug li 0.08%, pab tiv thaiv pitting, crevice corrosion thiab chloride stress corrosion cracking thaum tswj corrosion kuj tom qab vuam.
Cov ntaub ntawv qhia tau hais tias C276 tuaj yeem ua tiav cov nqi corrosion qis dua 0.1 mm / xyoo hauv cov ntsiab lus hydrochloric -acid concentration thiab kub ntau yam. Weld-kev ntsuam xyuas hlau hauv 10–15% HCl ntawm 38℃qhia txog corrosion ntawm li 0.20–0.22 mm / xyoo.
Cov yam ntxwv no ua rau ASTM B622 Hastelloy C276 raj tsim nyog rau cov khoom siv hluav taws xob sib hloov hluav taws xob, cov reactors, cov kua qaub hloov kab thiab cov txheej txheem piping qhov twg corrosion stability thiab weld kev ntseeg siab yog qhov tseem ceeb.
