321 Seamless Stainless Hlau Yeeb Nkab
321 seamless stainless hlau yeeb nkab
Nrog zoo corrosion tsis kam nyob rau hauv cov huab cua, 321 austenitic stainless hlau yog dav siv nyob rau hauv petrochemical, hluav taws xob fais fab, choj thiab tsheb kev lag luam [1] .Tab sis stainless hlau" stainless hlau" tsis yog tsis txaus, vim tias qhov tshwj xeeb kev pabcuam ib puag ncig, stainless hlau tseem yuav tshwm sim corrosion.Medium concentration, pH tus nqi, kub thiab lwm yam yuav muaj kev cuam tshuam ntau dua ntawm kev xeb ntawm stainless hlau.Piv txwv li, siv sijhawm ntev. ntawm 450 ~ 850 ℃ sensitization kub ntau yam, stainless hlau yuav tshwm sim intercrystalline corrosion.Qhov mechanism yog tias C khi rau Cr ntawm thaj tsam lis los tsim Cr23C6 thiab precipitates, txo Cr ntsiab lus ntawm thaj tsam lis, uas yog hu ua" chrome- tsis zoo" .Cr keeb yog ib qho ntawm cov khoom tseem ceeb los tiv thaiv intercrystalline corrosion. Thaum Cr cov ntsiab lus ntawm lis ciam teb tsawg dua 12%, qhov tshwm sim ntawm intercrystalline xeb yuav nce ntxiv.
Ob peb qhov tseem ceeb ntawm Alloy 321 Cov kav dej yog tias lawv tus nqi tsim nyog, haum pov thawj, lub zog loj thiab lub neej ntev kev pab cuam. Hom 321 Cov kav dej muaj cov qauv zoo thiab vuam muaj peev xwm, thiab tau siv dav hauv kev khiav qhov kub thiab txias. Peb cov kab ntawm Alloy 321 Cov Tub Ntxhais tau txais txiaj ntsig zoo los ntawm peb cov neeg siv vim nws cov khoom zoo xws li kev kawm tsim, ua haujlwm ceev, kev pab lub neej ntev, dim kev tiv thaiv, kev teeb tsa zoo meej thiab xeb kuj.
