Dab tsi yog 4 yam ntawm cov hlau tsis huv?

Raws li koj yuav lossis tsis paub, muaj ntau yam sib txawv ntawm cov hlau tsis muaj xim nyob hauv khw hnub no. Tom qab tag nrho, txhawm rau txiav txim siab cov hlau tsis huv, txhua cov hlau hlau yuav tsum muaj tsawg kawg 10.5% chromium; tons ntawm cov hlau phom muaj cov qib chromium no.

Txhua hom sib txawv ntawm cov hlau tsis huv muaj nws tus kheej qhov zoo, tab sis kuj nws tus kheej qhov tsis zoo. Feem ntau, txhua hom hlau tsis huv tau muab cais ua ib ntawm plaub pawg. Cov pab pawg no muaj raws li hauv qab no:

1. Austenite

Qhov feem ntau hom stainless hlau yog austenitic stainless hlau. Piv nrog rau lwm hom hlau tsis huv, austenitic stainless hlau muaj cov ntsiab lus nickel siab heev. Feem ntau, lawv kuj muaj cov chromium loj, nitrogen thiab molybdenum.

Austenitic steel tau paub txog nws lub peev xwm vuam siv tau siab thiab ductility. Feem ntau siv rau cov tais diav hauv chav ua noj thiab ntim khoom, lawv kuj tau qhuas ntau rau lawv lub peev xwm.

Lawv feem ntau muaj kev tiv thaiv corrosion siab heev. Qhov no yog qhov tsim nyog rau lawv siv hauv ntau daim ntawv thov uas ib puag ncig muaj xeb tshwm sim. Cov hlau austenitic stainless hlau suav nrog cov hlau 304 thiab 904L (N08904). Tib qhov teeb meem muaj peev xwm nrog austenitic stainless hlau yog lawv tus nqi siab.

2. Ferrite

Ferritic stainless hlau yog cov hlau tsis muaj hlau uas muaj cov ntsiab lus carbon tsawg tab sis cov nqi uas twb muaj lawm. Feem ntau, cov pa roj carbon ntau hauv ferritic stainless hlau tsis tshaj 0.10%. Txawm hais tias lwm cov ntxhia tuaj yeem ntxiv rau cov hlau no (molybdenum yog ib qho ntxiv), lawv feem ntau yog tsim los ntawm chromium.

Ferritic stainless hlau yog sib nqus thiab tau siv dav vim tias nws tiv taus kev nyuaj siab corrosion tawg. Yog li ntawd, lawv feem ntau siv hauv cov khoom lag luam uas cuam tshuam nrog cov khoom muaj peev xwm xeb. Cov khoom no suav nrog cov khoom pib, cov tais diav hauv chav ua noj thiab cov chaw lag luam.

Ob qhov ntau dua cov hlau ferritic yog cov hlau 430 thiab 434.

3. Ob lub tsev

Duplex stainless hlau yog qhov tseem ceeb ua ke ntawm ferritic stainless hlau thiab austenitic stainless hlau. Lub zog muaj siab dua ferritic thiab austenitic stainless hlau. Cov hlau, lawv cov ntsiab lus nickel qis dua cov hlau austenitic. Yog li ntawd, lawv kuj tseem pheej yig dua li cov hlau austenitic.

Duplex stainless hlau tau siv dav hauv kev lag luam roj av hauv qab. Qhov no feem ntau yog vim nws qhov kev tiv thaiv xeb, uas ua rau nws tiv taus qhov xeb ntawm cov ntsev ntsev tau ntev.

Duplex stainless hlau nrog kev txiav txim siab ntau thiab weldability tuaj yeem tsim ua ntau qhov sib txawv. Ob hom ntau hom duplex stainless hlau suav nrog S31803 stainless hlau thiab S32205 stainless hlau.

4. Martensite

Martensitic stainless hlau zoo ib yam hauv cov qauv rau ferritic stainless hlau, qhov sib txawv tiag tiag yog lawv cov feem pua. Txawm hais tias cov pa roj carbon feem pua ​​hauv ferritic stainless hlau tseem qis dua 0.10%, cov pa roj carbon feem pua ​​hauv martensitic stainless hlau hovers ncig 1%.

Qhov sib txawv ntawm cov pa roj carbon feem pua ​​yog qhov tseem ceeb vim tias nws tso cai rau martensitic stainless hlau kom tawv rau qhov loj. Hom hlau no feem ntau yog siv qhov twg muaj zog tab sis xav tau qhov nruab nrab tiv thaiv xeb. Koj feem ntau yuav pom nws siv hauv cov li qub lossis cov twj, txawm hais tias muaj ntau daim ntawv thov ntxiv.

Qee cov martensitic stainless hlau suav nrog cov hlau 431 thiab 420S45.
