◉Hauv lub neej niaj hnub no, cov hlau tsis xeb tau dhau los ua cov khoom siv tseem ceeb thiab siv dav hauv kev tsim kho, kev tsim khoom thiab lub neej txhua hnub. Muaj ntau hom hlau tsis xeb sib txawv, suav nrog cov qauv zoo li 201, 304 thiab316.
Txawm li cas los xij, rau cov neeg uas tsis nkag siab txog cov khoom ntawm cov khoom siv, nws yooj yim kom tsis meej pem los ntawm qhov sib txawv ntawm cov qauv no. Tsab xov xwm no yuav piav qhia txog qhov sib txawv ntawm cov hlau tsis xeb 201, 304 thiab 316 los pab cov nyeem ntawv nkag siab zoo dua txog cov qauv sib txawv ntawm cov khoom siv hlau tsis xeb thiab muab qee cov lus qhia rau kev yuav cov hlau tsis xeb.
◉Ua ntej, qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau tsis xeb yog ib qho tseem ceeb hauv kev txiav txim siab nws cov kev ua tau zoo thiab cov yam ntxwv.Hlau tsis xeb 201, 304 thiab 316 muaj qhov sib txawv pom tseeb hauv cov tshuaj lom neeg. Cov hlau tsis xeb 201 muaj 17.5% -19.5% chromium, 3.5% -5.5% nickel, thiab 0.1% -0.5% nitrogen, tab sis tsis muaj molybdenum.
Ntawm qhov tod tes, cov hlau tsis xeb 304 muaj 18% -20% chromium, 8% -10.5% nickel, thiab tsis muaj nitrogen lossis molybdenum. Qhov sib piv, cov hlau tsis xeb 316 muaj 16% -18% chromium, 10% -14% nickel, thiab 2% -3% molybdenum. Los ntawm cov tshuaj lom neeg sib xyaw, cov hlau tsis xeb 316 muaj kev tiv thaiv corrosion thiab acid ntau dua, tsim nyog siv rau hauv qee qhov chaw tshwj xeeb dua li cov hlau tsis xeb 201 thiab 304.
◉Qhov thib ob, qhov sib txawv ntawm kev tiv thaiv corrosion
Kev tiv thaiv xeb yog qhov qhia txog kev ua tau zoo tseem ceeb ntawm cov hlau tsis xeb. Cov hlau tsis xeb 201 muaj kev tiv thaiv xeb zoo rau feem ntau cov organic acids, inorganic acids thiab cov tshuaj ntsev ntawm chav tsev kub, tab sis yuav raug xeb hauv qhov chaw alkaline muaj zog. Cov hlau tsis xeb 304 muaj kev tiv thaiv xeb zoo thiab tsim nyog rau feem ntau cov chaw corrosive dav dav.
Ntawm qhov tod tes, cov hlau tsis xeb 316 zoo heev hauv kev tiv thaiv xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw acidic thiab cov xwm txheej kub siab nrog kev tiv thaiv xeb zoo heev, feem ntau siv rau hauv tshuaj lom neeg, dej hiav txwv thiab lwm yam kev siv. Yog li ntawd, thaum yuav cov khoom siv hlau tsis xeb, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov qauv zoo raws li kev siv tshwj xeeb ntawm ntau qhov chaw sib txawv.
◉Qhov thib peb, qhov sib txawv ntawm cov khoom siv kho tshuab
Cov khoom siv kho tshuab ntawm cov hlau tsis xeb muaj xws li cov cim qhia xws li lub zog, ductility thiab hardness. Feem ntau hais lus, lub zog ntawm stainless hlau 201 yog me ntsis siab dua li ntawm stainless hlau 304, tab sis qis dua li ntawm stainless hlau 316. Stainless hlau 201 thiab 304 muaj ductility zoo, yooj yim rau kev ua thiab molding, tsim rau qee qhov kev ua haujlwm ntawm cov khoom siv ntawm cov xwm txheej siab dua.
Lub zog ntawm stainless hlau 316 siab dua, tab sis kuj muaj kev tiv thaiv kev hnav thiab tensile zoo, tsim nyog rau kev ua haujlwm siab thiab qhov kub siab. Yog li ntawd, thaum xaiv cov khoom siv stainless hlau, koj yuav tsum xaiv raws li qhov xav tau tshwj xeeb thiab kev siv ib puag ncig.
◉Plaub, qhov sib txawv ntawm tus nqi
Kuj tseem muaj qee qhov sib txawv ntawm tus nqi ntawm cov hlau tsis xeb 201, 304 thiab 316. Feem ntau hais lus, tus nqi ntawm cov hlau tsis xeb 201 yog qis dua, pheej yig dua. Tus nqi ntawm cov hlau tsis xeb 304 yog siab dua, tab sis vim nws muaj ntau yam kev siv thiab kev ua tau zoo dua, nws tseem yog ib qho ntawm cov qauv hlau tsis xeb feem ntau hauv khw.
◉ Stainless hlau 316 kim heev vim nws zoo tiv taus corrosion thiab cov khoom siv kho tshuab, thiab nws tsim nyog rau qee qhov chaw tshwj xeeb uas xav tau cov khoom siv siab. Yog li ntawd, thaum yuav cov khoom siv stainless hlau, koj yuav tsum xav txog cov yam ntxwv xws li kev ua tau zoo ntawm cov khoom siv thiab cov peev nyiaj.
