1.What yog qhov sib txawv ntawm cov tshuaj lom neeg li cas?
DC01 cov ntsiab lus carbon tsis pub tshaj 0.12%, nws cov ntsiab lus manganese tsis tshaj 0.60%, thiab nws cov ntsiab lus phosphorus thiab cov leej faj ncauj tsis tshaj 0.045%. DC07 muaj cov ntsiab lus ntau tshaj plaws ntawm 0.01%, qhov siab tshaj plaws manganese cov ntsiab lus ntawm 0.2%, thiab cov lus hais txog cov txiv neej ntawm 0.02% txhua. Nws tseem muaj qhov siab tshaj plaws ntawm 0.2% titanium, uas pab txhawm rau cov noob txhuv loj thiab txhim kho cov hlau yas thiab tawv.
2.What yog qhov sib txawv ntawm cov neeg kho tshuab?
DC01 feem ntau muaj cov txiaj ntsig lub zog ntawm 140Mpa thiab 280Mpa, lub zog tensile ntawm 270Mpa thiab 410mpa, thiab kev mus elongation tsawg kawg 28%. DC07 muaj ib qho txiaj ntsig lub zog ntawm kwv yees li 150MPA, lub zog tensile ntawm 2510mpa thiab 310MPA, thiab ib qho elongation ntawm kwv yees li ntawm 44%. Hauv kev sib piv, DC07 muaj tsawg dua lub zog, siab dua elongation, thiab zoo dua yas thiab ductility.
3.Qhov twg yog qhov sib txawv ntawm cov yam ntxwv ua kom zoo?
DC01 muaj qee qhov kev teeb tsa kev sib sib zog nqus zoo thiab feem ntau yog siv rau kev ua haujlwm txias yooj yim xws li muaj dabtsi yog dabtsi yog khoov kev yooj yim. DC07 yog super - Kev sib sib zog nqus steel thiab yog ib qho ntawm cov kev sib sib zog nqus sib sib zog nqus sib sib zog nqus cov kev xav tau.
4.What yog qhov sib txawv ntawm cov chaw thov?
DC01 tau siv dav hauv cov txheej txheem yooj yim hauv kev ua lag luam hauv tsheb, nrog rau cov vaj tsev thiab phab ntsa hauv kev tsim kho. Nws kuj tseem siv tau rau hauv cov cuab yeej siv hluav taws xob thiab cov cuab yeej siv hauv tsev. DC07 feem ntau siv nyob rau hauv kev lag luam automotive los tsim tsim cov stamping complex stamping seem, xws li auto ntoo panels. Nws tseem siv nyob rau hauv Aerospace kev lag luam los tsim siab heev - ductant Cheebtsam, thiab tseem siv tau los tsim cov tsev nyob hauv hluav taws xob.
5.Qhov yog lub corrosion tsis kam ntawm dc01 thiab dc07 txias rolled steel?
Tsis muaj zog ua xeb: Ob leeg yog tsawg}} Cov hlau carbon thiab carbon thiab carbon monoxs, tsis muaj kev ntxias ntawm cov hlau thiab carbon, uas muaj cov roj carbon ntau zoo li chromium thiab npib tsib xee. Yog li ntawd, lawv tau raug rau electrochemical corrosion (xeb) nyob rau hauv ib puag ncig nrog noo noo thiab cov pa paug (xws li pa thiab muaj sab xis). Lawv txoj kev txhim kho corrosion yog qhov tseem ceeb tib yam, tsis muaj qhov sib txawv sib txawv, thiab ob qho tib si yog tsis suav hais tias tsis yog {{5 {5 5} {tiv taus cov hlau.
Corrosion Qhia: Nyob hauv lub ntuj ib puag ncig, thaum raug cua thiab noo, hlau oxide (xeb) maj mam ua rau saum npoo. Cov xoob txheej xeb tsis muaj peev xwm tiv thaiv tsis taus kev xeb ntxiv ntawm cov hlau hauv qab. Ntev {-}}} siv tau yuav ua rau txo qis hauv cov ntaub tuab thiab lub zog.
