1, kev ua tau zoo ntawm ntau hom ntawm seamless steel kav ntawm tsawg kub
Carbon Steel Seamless steel yeeb nkab:
Carbon Steel Seamless steel kav yog tsim nyog rau kev ua hauj lwm kub feem ntau xws li {}} 29℃rau 425 degree. Thaum qhov kub kom txog qhov kev txwv kub tsawg ntawm -29 degree, cov tawv nqaij tawv, cov khoom yuav tsawg, uas yuav ua rau mob khaub thuas txias. Hauv qhov tsawg-ib puag ncig tsawg-ib puag ncig, yog tias raug rau sab nraud cuam tshuam lossis lwm yam kev mob, cov kav hlau yuav yauv mus rau lwm tus, cuam tshuam rau lawv txoj kev siv thiab kev nyab xeeb.
Q355 Seamless Steel Yeeb:
Q355 Seamless steel yeeb nkab muaj kev ua tau zoo heev thiab tuaj yeem tiv taus qis qis. Txawm li cas los xij, qhov qis qis - kub kev ua tau kuj tseem yuav cuam tshuam los ntawm nws qib ib, B, C, D, thiab E). Ntawm qhov chaw kub tsawg, nws cov khoom siv neeg (xws li ua lub zog, thiab lwm yam) tuaj yeem tswj hwm tus qauv kev ruaj ntseg ntawm cov yeeb nkab steel. Txawm li cas los xij, raws li qhov ntsuas kub tsawg dua, nws cov khoom tseem yuav hloov. Piv txwv li, cov qauv ntawm cov txiaj ntsig tau nce zuj zus mus nrog kev nce siab ntawm cov raj ntsuas phab ntsa qis, thiab qhov kub tsawg tuaj yeem muaj qee yam cuam tshuam rau nws txoj kev nruj.
106b Seamless Steel Yeeb:
106b Seamless Steel kav yog feem ntau siv nyob rau hauv ib qho kub ntau ntawm - 20 Qib rau 400 Qib. Nyob rau hauv cov cheeb tsam txias hauv qab-5 degree, uas yog, hauv kev muaj zog qis, cov tawv nqaij tawv ntawm cov hlau yuav tsis muaj zog thiab cuam tshuam rau qhov tshwm sim. Txawm hais tias nws tseem tuaj yeem siv tau ntau zaus ntawm qhov kub tsawg, kev saib xyuas rau qhov teeb meem no txias, thiab cov ntaub ntawv tsim nyog thiab cov txheej txheem tsim nyog thiab cov txheej txheem kom ntseeg tau tias nws txias tsis kam.
2, kev ua tau zoo ntawm ntau hom ntawm seamless steel kav ntawm qhov kub
Carbon Steel Seamless steel yeeb nkab:
Carbon Steel Seamless steel kav yuav yauv oxidation thiab corrosion ntawm qhov kub. Nws qhov kev ua haujlwm kub yog feem ntau ntawm -29℃thiab 425 degree. Thaum nws mus ze lossis tshaj qhov txwv ntawm qhov ntsuas kub no, cov oxidation tiv thaiv oxide txheej thiab ua kom nrawm dua rau ntawm cov yeeb nkab roj, cuam tshuam nws cov kev ua tau zoo thiab kev pabcuam lub neej. Nyob rau tib lub sijhawm, siab kub yuav ua rau deformation ntawm cov kav hlau steel vim yog cov khoom xws li thermal nthuav kev coefficiention. Yog tias muaj kev ntxhov siab, nws yuav cuam tshuam rau nws cov qauv kev ruaj ntseg thiab tseem ua rau cov xwm txheej txaus ntshai xws li tawg.
Alloy Steel Seamless Steel Yeeb:
Qhov ntsuas kub ntau rau Alloy Steel Seamless Steel Kav (xws li feem ntau ntawm - 29 qib, haum rau qhov kub thiab kub siab ua haujlwm ib puag ncig. Noj 10cmoal steelless steel yeeb ua piv txwv, nws yog cov hlau tsawg-alloy nrog ntau qhov chaw nyob hauv qhov chaw kub siab:
Kev kub siab kub lub zog: nws tuaj yeem tswj cov neeg kho tshuab siab thiab tensile nyob rau hauv cov pa hluav taws xob ruaj khov, kom yooj yim deformed lossis puas nyob rau hauv ua hauj lwm ib puag ncig muaj kub thiab kub siab.
Oxidation tsis kam: cov chromium lub caij hauv nws tuaj yeem tsim cov tshuaj oxidation dension, yog li ncua kev ncua ntawm oxidation ntawm kev ua tau zoo thiab kev pabcuam lub neej ntawm cov yeeb nkab steel.
Kev Cwj Pwm: Thaum muaj kev coj tus cwj pwm kub, cov khoom siv nkag mus, yog tias muaj kev nyab xeeb rau qhov chaw qis thiab muaj kev ntxhov siab rau qhov chaw nyob ntev thiab kub.
Coefficient ntawm thermal expansion: Hom kab hlau no muaj cov teeb meem loj dua, thiab cuam tshuam nws cov kev sib txuas nrog lwm cov khoom vim muaj kev ntxhov siab thiab kev sib zog.
Stainless hlau seamless steel yeeb nkab:
Qhov ntsuas kub ntau rau kev siv ntawm seamless stainless hlau kav tawm tsam nyob ntawm cov khoom thiab alloy muaj pes tsawg leeg ntawm cov hlau stainless. Cov ntaub ntawv tsis sib xws muaj li 304, 316, thiab lwm yam yog feem ntau ntawm {}} 254℃thiab 816 degree. Stainless Hlau Seamless Steel Kav Muaj zoo corrosion tsis kam thiab siab - sov qhov chaw ib puag ncig, ua rau lawv haum rau qee thaj teb tshwj xeeb muaj. Piv txwv li, hauv kev lag luam xws li cov tshuaj lom neeg engineering, thaum kev cuam tshuam nrog cov kav dej siab thiab tswj cov qauv sib xyaw thiab tswj hwm lawv cov kev ruaj khov ntawm qhov kub.
Seamless steel yeeb nkab 513:
Seamless steel yeeb nkab 513 muaj cov kub ua kom haum thiab feem ntau yog siv rau hauv ib qho kub thiab txias rau ib puag ncig ntawm cov chaw nyob hauv cov liaj teb xws li roj av, tshuaj lom neeg, thiab lub zog. Piv txwv li, hauv high - kev tiv thaiv kub, nws tuaj yeem tiv thaiv kev nyab xeeb ntawm ntau yam kev tawm tsam muaj zog (xws li lwm yam kev ua haujlwm ntawm cov khoom siv nyob rau hauv high -} kub kev tshua.
Txias Draws Seamless Steel Yeeb:
Txias drawn seamless steel kav muaj lub siab melting kub, tuaj yeem tiv thaiv siab kub thiab txias qhov chaw ib puag ncig, thiab tsis yooj yim deformed lossis tawg. Vim tias siv cov khaub thuas txias, cov qauv ntawm cov kav hlau yog denser, uas pab lawv tswj cov qauv kev ruaj khov nyob hauv ib puag ncig kub. Tom qab kev tawm tsam tshwj xeeb - corrosion kho, lawv kuj tseem tuaj yeem muaj zog corrosion tsis kam nyob rau hauv ib puag ncig nrog kub thiab muaj peev xwm corrosive.
