Hlau:Hais txog cov ntsiab lus carbon ntawm 0.02% txog 2.11% ntawm cov hlau thiab cov hlau sib xyaw ua ke, vim nws tus nqi qis, kev ua tau zoo txhim khu kev qha, yog qhov siv dav tshaj plaws, cov khoom siv hlau ntau tshaj plaws. Cov qauv tsim kho tshuab tsis yog tus qauv ntawm cov hlau siv dav tshaj plaws yog: Q235, 45 # hlau, 40Cr, stainless hlau, pwm hlau, caij nplooj ntoos hlav hlau thiab lwm yam.
Kev faib tawm ntawm cov hlau qis-carbon, nruab nrab-carbon thiab cov hlau carbon siab:qis < nruab nrab (0.25% txog 0.6%) < siab
Q235-A:Cov hlau carbon tsawg nrog cov ntsiab lus carbon <0.2%, qhia tias lub zog tso zis yog 235MPa, uas muaj cov yas zoo, qee lub zog tab sis tsis cuam tshuam. Kev tsim qauv tsis yog tus qauv feem ntau yog siv rau cov khoom sib txuas.
45 # hlau:Cov ntsiab lus carbon ntawm 0.42 ~ 0.50% ntawm cov hlau carbon nruab nrab, nws cov khoom siv kho tshuab, kev ua haujlwm txiav zoo heev, kev ua haujlwm vuam tsis zoo.45 steel tempering (quenching + tempering) hardness ntawm HRC20 ~ HRC30, quenching hardness feem ntau xav tau HRC45 hardness tom qab lub zog siab ruaj khov tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
40Cr:Kev kho mob tom qab tempering muaj cov khoom siv kho tshuab zoo, tab sis weldability tsis zoo, yooj yim tawg siv tau los ua cov iav, txuas rods, shafts, thiab lwm yam, quenched nto hardness txog li HRC55.
Cov hlau tsis xeb SUS304, SUS316:Cov hlau no yog cov hlau uas muaj cov pa roj carbon tsawg tsawg nrog cov pa roj carbon tsawg dua 0.08%. Muaj kev tiv thaiv corrosion zoo, cov khoom siv kho tshuab, stamping thiab bending kub ua haujlwm tau zoo, tus qauv SUS304 tsis yog hlau nplaum. Txawm li cas los xij, ntau yam khoom vim yog kev sib cais ntawm cov khoom sib xyaw lossis kev kho cua sov tsis zoo thiab lwm yam laj thawj, ua rau muaj hlau nplaum, xws li qhov xav tau cov hlau nplaum tsis yog hlau nplaum yuav tsum tau piav qhia hauv cov duab kos engineering. SUS316 muaj zog tiv thaiv corrosion ntau dua 304, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias thiab qhov chaw nyuaj. Tam sim no, muaj ntau 316L hauv kev ua lag luam, vim nws cov pa roj carbon tsawg dua, nws qhov kev ua haujlwm vuam, kev ua haujlwm zoo dua SUS316. Cov hlau ntawv hauv cov qauv tsim tsis yog tus qauv feem ntau siv los ua cov khoom me me ntawm lub hau sab nraud, sensors, thiab lwm yam khoom txheem ntawm lub rooj zaum mounting, phaj chav kawm tuaj yeem siv rau kev sib txuas qhov chaw.
Txhuas:AL6061, AL7075, 7075 txhuas phaj yog cov phaj txhuas nyuaj heev, qhov nyuaj yog siab dua 6061. Tab sis tus nqi ntawm 7075 yog siab dua 6061. Tag nrho lawv tuaj yeem kho nrog cov tshuaj anodic oxidation ntuj, sandblasting oxidation, hard oxidation, nickel plating thiab lwm yam. Cov khoom ua tiav dav dav nrog cov tshuaj anodic oxidation ntuj, tuaj yeem ua kom tiav qhov loj me. Sandblast oxidation muaj qhov zoo dua, tab sis tsis tuaj yeem lav qhov tseeb siab. Yog tias koj xav ua kom cov khoom txhuas zoo li hlau, cov khoom tuaj yeem ua nickel-plated. Qee cov khoom txhuas uas sib cuag ncaj qha nrog cov khoom, xws li kev nplaum, kev tiv taus kub siab thiab qis, qhov yuav tsum tau rwb thaiv tsev tuaj yeem suav tias yog Teflon plating.
Tooj dag:yog tsim los ntawm tooj liab thiab zinc alloy, hnav tsis kam muaj zog hnav tsis kam. H65 tooj dag yog tsim los ntawm 65% tooj liab thiab 35% zinc, vim nws muaj cov txheej txheem zoo, thev naus laus zis, kev ua haujlwm kub thiab txias, thiab cov tsos ntawm kub, tsis yog tus qauv kev lag luam ntau dua, siv rau qhov xav tau hnav-resistant tsos ntawm cov kev xav tau siab ntawm lub sijhawm.
Tooj liab:Tooj liab rau tooj liab monomers, nws qhov tawv thiab qhov nyuaj yog qhov tsis muaj zog dua li tooj dag, tab sis zoo dua thermal conductivity. Siv rau hauv cov thermal conductivity thiab hluav taws xob conductivity xav tau ntawm cov xwm txheej siab. Piv txwv li, laser vuam ib feem ntawm lub taub hau vuam.
