Tus lej code rau hastelloy C276 yog dab tsi?
Pov thawj kev ua tau zoo nyob rau hauv ntau yam tshuaj corrosive rau ntau tshaj 50 xyoo
HASTELLOY C-276 alloy (UNS N10276) yog thawj wrought nickel-chromium-molybdenum cov khoom siv los txo cov teeb meem vuam (los ntawm kev tsim txiaj ntawm nws cov ntsiab lus tsis tshua muaj carbon thiab silicon). Raws li qhov tshwm sim, nws tau txais dav hauv kev ua tshuaj lom neeg thiab kev lag luam ntsig txog thiab muaj cov ntaub ntawv pov thawj ntawm kev ua tau zoo hauv ntau yam tshuaj corrosive rau ntau tshaj 50 xyoo.
Zoo li lwm cov nickel alloys, nws yog ductile, yooj yim rau kev tsim thiab weld, thiab muaj kev tiv thaiv zoo heev rau kev ntxhov siab corrosion cracking (ib daim ntawv ntawm degradation uas austenitic stainless hlau raug cuam tshuam) hauv cov kev daws teeb meem uas muaj chlorides. Nrog nws cov ntsiab lus chromium thiab molybdenum siab, nws tiv taus oxidizing thiab tsis-oxidizing acids thiab nthuav tawm zoo heev rau pitting thiab crevice corrosion nyob rau hauv muaj chlorides thiab lwm yam halides. Tsis tas li ntawd, nws muaj peev xwm tiv taus sulfide kev ntxhov siab tawg thiab kev ntxhov siab corrosion tawg hauv qhov chaw qaub oilfield.
HASTELLOY C-276 alloy muaj nyob rau hauv phaj, ntawv, sawb, billet, pas nrig, hlau, raj, raj thiab clad electrode daim ntawv. Cov txheej txheem tshuaj lom neeg kev lag luam (CPI) cov ntawv thov suav nrog cov tshuab hluav taws xob, cov khoom siv hluav taws xob, thiab cov kab.
