Hlau:hais txog cov ntsiab lus carbon ntawm 0.02% mus rau 2.11% ntawm cov hlau thiab carbon alloys sib sau ua ke, vim nws cov nqi qis, txhim khu kev qha kev ua tau zoo, yog qhov siv dav tshaj plaws, cov khoom siv hlau loj tshaj plaws. Tsis yog-tus qauv tsim ntawm cov hlau uas siv dav tshaj plaws yog: Q235, 45 # steel, 40Cr, stainless hlau, pwm hlau, steel hlau thiab lwm yam.
Kev faib tawm ntawm cov pa roj carbon tsawg, nruab nrab-carbon thiab high-carbon steels:qis < nruab nrab (0.25% rau 0.6%) < siab
Q235-A:Cov pa roj carbon tsawg nrog cov ntsiab lus carbon <0.2%, qhia tias lub zog tawm los yog 235MPa, uas muaj cov yas zoo, qee lub zog tab sis tsis muaj kev cuam tshuam. Tsis yog-tus qauv tsim feem ntau yog siv rau welded structural Cheebtsam.
45 # steel:Cov ntsiab lus carbon ntawm 0.42 ~ 0.50% ntawm cov pa roj carbon nruab nrab, nws cov khoom siv kho tshuab, kev ua haujlwm zoo heev, kev ua haujlwm tsis zoo welding.45 steel tempering (quenching + tempering) hardness ntawm HRC20 ~ HRC30, quenching hardness feem ntau xav tau HRC45 hardness tom qab siab zog stability tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
40 Cr:kev sib ntsib nyob rau hauv lub alloy structural steel. Tom qab tempering kev kho mob muaj cov khoom zoo, tab sis weldability tsis zoo, yooj yim rau tawg yuav siv tau los ua iav, txuas rods, shafts, thiab lwm yam., quenched nto hardness mus txog HRC55.
Stainless hlau SUS304, SUS316:Cov pa roj carbon tsawg nrog cov ntsiab lus carbon ≤ 0.08% Nws muaj kev tiv thaiv corrosion zoo, cov khoom siv kho tshuab, stamping thiab dabtsi yog khoov kub ua haujlwm, tus qauv SUS304 tsis-magnetic. Txawm li cas los xij, ntau yam khoom vim yog smelting muaj pes tsawg leeg sib cais los yog kev kho cua sov tsis zoo thiab lwm yam laj thawj, ua rau cov hlau nplaum, xws li qhov xav tau ntawm cov hlau nplaum uas tsis yog hlau nplaum yuav tsum muaj nyob rau hauv engineering drawings los piav qhia.SUS316 tshaj 304 corrosion kuj muaj zog, tshwj xeeb tshaj yog nyob rau hauv high kub thiab hnyav ib puag ncig. Tam sim no, muaj ntau yam 316L ntawm kev ua lag luam, vim nws cov ntsiab lus qis dua, nws cov kev ua haujlwm vuam, kev ua haujlwm zoo dua SUS316. sheet hlau nyob rau hauv cov qauv uas tsis yog-tus qauv feem ntau yog siv los ua qhov me me ntawm lub hau npog, sensors, thiab lwm yam qauv ntawm lub rooj zaum mounting, phaj phaj tuaj yeem siv rau qhov sib txuas.
Aluminium:AL6061, AL7075, 7075 txhuas phaj belongs rau super nyuaj aluminium phaj, hardness yog siab tshaj 6061. Tab sis tus nqi ntawm 7075 yog ntau dua 6061. Tag nrho cov ntawm lawv tuaj yeem kho nrog ntuj anodic oxidation, sandblasting oxidation, nyuaj oxidation, npib tsib xee plating thiab lwm yam. Kev ua haujlwm dav dav nrog ntuj anodic oxidation, tuaj yeem ua kom tiav qhov loj me. Sandblast oxidation muaj cov tsos zoo dua, tab sis tsis tuaj yeem lav qhov siab. Yog tias koj xav ua aluminium qhov chaw muaj qhov zoo ntawm cov hlau qhov chaw tuaj yeem ua npib tsib xee-plated. Qee qhov txhuas qhov chaw uas yog nyob rau hauv kev sib cuag nrog cov khoom, xws li adhesion, siab thiab tsis kub tsis kam, rwb thaiv tsev yuav tsum tau txiav txim siab 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 tias nws muaj cov tshuab zoo, thev naus laus zis, kev ua haujlwm kub thiab txias, thiab cov tsos ntawm golden, tsis yog qauv kev lag luam daim ntawv thov ntau dua, siv nyob rau hauv kev xav tau rau hnav-resistant tsos ntawm lub siab xav tau ntawm lub ntees.
Ntshav tooj liab:ntshav tooj liab rau tooj liab monomers, nws nruj thiab hardness yog weaker tshaj tooj dag, tab sis zoo thermal conductivity. Siv nyob rau hauv thermal conductivity thiab hluav taws xob conductivity yuav tsum tau ntawm siab zaus. Piv txwv li, laser vuam ib feem ntawm lub vuam taub hau ib feem.
