Cov hlau tsis xeb yog ib yam khoom siv tau ntau yam uas siv dav hauv ntau yam lag luam vim nws tiv taus xeb, muaj zog thiab zoo nkauj. Ntawm ntau qib muaj, cov hlau tsis xeb 201, 430, 304 thiab 310 sawv tawm rau lawv cov yam ntxwv thiab kev siv tshwj xeeb.
Hlau tsis xeb 201yog ib qho pheej yig dua rau 304 thiab feem ntau yog siv rau hauv cov ntawv thov uas tsis yog qhov tseem ceeb uas yuav tsum xav txog kev tiv thaiv xeb. Nws muaj cov manganese ntau dua thiab cov nickel tsawg dua, ua rau nws pheej yig dua, tab sis kuj muaj cov antioxidant tsawg dua. Cov ntawv thov feem ntau suav nrog cov khoom siv hauv chav ua noj, cov khoom siv hauv tsheb, thiab qee yam khoom siv hauv tsev.
Hlau tsis xeb 430yog qib hlau ferritic, paub txog nws qhov kev tiv thaiv corrosion zoo thiab formability. Nws yog magnetic thiab feem ntau siv rau hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion nruab nrab. Cov kev siv ib txwm muaj xws li cov khoom siv hauv chav ua noj, tsheb trim, thiab cov pa tawm. Nws lub peev xwm los tiv taus qhov kub siab kuj ua rau nws haum rau qee yam kev siv hauv kev lag luam.
Hlau tsis xeb 304Ib qho ntawm cov hlau tsis xeb uas siv dav tshaj plaws, paub txog nws qhov kev tiv taus xeb zoo heev thiab weldability. Nws muaj cov nickel ntau dua, uas ua rau nws ruaj khov dua. Cov qib no feem ntau pom muaj nyob rau hauv cov khoom siv ua zaub mov, cov thawv tshuaj thiab cov ntawv thov kev tsim kho. Nws cov khoom tsis muaj hlau nplaum ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev huv thiab kev zoo nkauj.
Hlau tsis xeb 310yog ib hom hlau austenitic uas tsim los rau kev siv kub heev. Nws muaj kev tiv thaiv oxidation zoo heev thiab feem ntau siv rau hauv qhov chaw kub heev xws li cov khoom siv hauv lub cub tawg thiab cov khoom siv hloov pauv cua sov. Nws lub peev xwm los tiv taus cov xwm txheej hnyav ua rau nws yog qhov kev xaiv zoo rau kev lag luam aerospace thiab petrochemical.
Hauv kev xaus lus, kev xaiv cov hlau tsis xeb 201, 430, 304 thiab 310 nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov, suav nrog kev tiv taus corrosion, kev tiv taus kub thiab tus nqi. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv cov ntaub ntawv zoo rau txhua qhov project.
