Nyias-walled stainless hlau kav yog siv dav hauv kev lag luam thiab kev lag luam, nrog rau cov khoom siv feem ntau yog 304 thiab 316L stainless hlau. Ob lub stainless hlau no muaj zoo heev corrosion kuj thiab mechanical zog thiab yog li ntawd xaiv raws li cov ntaub ntawv ntawm kev xaiv rau nyias-walled stainless hlau kav. Hauv qab no kuv yuav piav qhia vim li cas thiaj xaiv 304 lossis 316L stainless hlau.

Ua ntej, cov kav hlau tsis muaj steel yuav tsum muaj kev tiv thaiv corrosion zoo vim tias lawv feem ntau siv los thauj ntau yam xov xwm, suav nrog kua, roj, thiab tshuaj lom neeg. 304 stainless hlau yog cov khoom siv stainless hlau uas muaj 18% chromium thiab 8% npib tsib xee. Cov tshuaj muaj pes tsawg leeg no muab 304 stainless hlau zoo heev corrosion kuj, ua rau nws resistant rau feem ntau corrosive media, xws li dej, acids, thiab alkalis. Yog li, 304 stainless hlau kav yog siv dav hauv kev lag luam thiab kev tsim kho.

Hauv kev sib piv, 316L stainless hlau muaj ntau dua corrosion kuj. Nws muaj 2-3% molybdenum, uas muab kev tiv thaiv ntxiv tiv thaiv corrosion. Qhov no tso cai rau 316L stainless hlau yeeb nkab ua tau zoo nyob rau hauv ib puag ncig hnyav, tshwj xeeb tshaj yog nyob rau hauv cov chloride ions lossis lwm yam corrosive gases. Yog li ntawd, 316L stainless hlau kav yog dav siv nyob rau hauv chemical, marine, thiab zaub mov kev lag luam, uas muaj ntau dua yuav tsum tau rau corrosion kuj.

Thib ob, cov kav hlau stainless kuj yuav tsum muaj cov khoom siv kho tshuab zoo kom tau raws li ntau yam kev xav tau. Ob leeg 304 thiab 316L stainless hlau muaj lub zog zoo thiab tawv, ua rau lawv tsim nyog rau cov kav dej hauv qhov chaw muaj kev kub ntxhov thiab kub. Tsis tas li ntawd, ob qho tib si cov ntaub ntawv yooj yim rau tshuab thiab vuam, muab kev tsim kom yooj yim dua.

Hauv cov ntsiab lus, kev xaiv ntawm 304 lossis 316L stainless hlau raws li cov khoom siv rau nyias-walled stainless hlau kav yog raws li nws cov corrosion kuj zoo heev thiab txhua yam khoom. Nyob ntawm cov kev xav tau tshwj xeeb thiab ib puag ncig, xaiv cov khoom siv stainless hlau tsim nyog tuaj yeem ua kom ntseeg tau thiab kav ntev ntawm koj cov kav dej.
