Lub hauv paus chiv keeb ntawm cov hlau tsis xeb tuaj yeem taug qab rov qab mus rau xyoo 1913, thaum tus kws tshawb fawb German Harris Krauss thawj zaug pom tias cov hlau uas muaj chromium muaj kev tiv thaiv corrosion zoo heev. Qhov kev tshawb pom no tau tso lub hauv paus rau cov hlau tsis xeb. Cov "hlau tsis xeb" thawj zaug yog cov hlau chromium, uas feem ntau yog siv rau hauv riam thiab cov tais diav. Xyoo 1920, kev siv cov hlau tsis xeb pib nthuav dav. Nrog rau kev nce ntxiv ntawm cov ntsiab lus chromium thiab nickel, qhov kev tiv thaiv corrosion thiab lub zog ntawm cov hlau tsis xeb tau zoo dua. Cov thev naus laus zis tsim khoom ntawmcov kav hlau tsis xebmaj mam loj hlob thiab tau pib siv rau hauv kev lag luam tshuaj lom neeg, roj av thiab kev ua zaub mov.
Cov kav dej hlau tsis xeb yog siv dav hauv kev lag luam kev tsim kho rau kev txhawb nqa cov qauv, kho kom zoo nkauj phab ntsa sab nraud,cov ntaiv thiab cov tes tuavVim nws txoj kev tiv thaiv xeb zoo heev thiab zoo nkauj, cov kav dej hlau tsis xeb yog qhov tsim nyog rau kev siv rau sab nraum zoov thiab huab cua hauv dej hiav txwv. Nws tsis tsuas yog tiv taus qhov kev sim ntawm huab cua hnyav xwb, tab sis nws kuj txo qhov xav tau kev saib xyuas, ua rau lub tsev ruaj khov thiab zoo nkauj dua.
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, cov thev naus laus zis ntawm cov kav dej hlau tsis xeb txuas ntxiv mus zoo dua, thiab ntau cov hlau ua tau zoo tau tshwm sim, xws lisuper stainless hlau yeeb nkab, cov kav dej hlau tsis xeb ob chav thiab lwm yam. Cov ntaub ntawv tshiab no ua tau raws li qhov xav tau ntawm kev lag luam thiab txhawb kev siv cov kav dej hlau tsis xeb hauv ntau qhov chaw. Kev txhim kho yav tom ntej yuav txuas ntxiv tsom mus rau kev txhim kho cov khoom siv thiab cov txheej txheem tsim khoom kom teb rau cov chaw siv nyuaj dua thiab kev xav tau ntawm kev ua lag luam.
Cov kev lag luam tshuaj lom neeg thiab tshuaj siv cov kav hlau tsis xeb los thauj cov tshuaj thiab cov tshuaj thiab los tswj ntau yam kua dej corrosive. Phab ntsa sab hauv du ntawm cov kav hlau tsis xeb tsis tsuas yog txo qhov kev ua qias tuaj ntawm cov kua hauv cov txheej txheem thauj mus los, tab sis kuj pab txhawb kev ntxuav thiab tua kab mob, ua kom ntseeg tau tias muaj kev huv ntawm cov txheej txheem ntau lawm thiab kev nyab xeeb ntawm cov khoom.
Hauv kev lag luam khoom noj thiab dej haus, cov kav hlau tsis xeb yog siv rau kev ua zaub mov, kev xa dej haus thiab kev ntim khoom. Nws cov khoom tsis muaj tshuaj lom, tiv taus corrosion thiab yooj yim ntxuav tau raws licov kev cai rau cov khoom noj khoom haus, xyuas kom meej tias cov zaub mov muaj kev nyab xeeb thiab kev huv ntawm cov txheej txheem tsim khoom. Tsis tas li ntawd, qhov ruaj khov ntawm cov kav hlau tsis xeb pab txo qhov zaus ntawm kev saib xyuas thiab hloov cov khoom siv.
