Dab tsi yog cov txiaj ntsig lub zog ntawm CR4?
Qhov siab tshaj plaws tawm lub zog ntawm CR4 hlau yog 210 MPa, nrog qhov tsawg kawg ntawm 38 feem pua ntawm 38 feem pua ntawm 38 feem pua ntawm qhov siab tshaj ntawm 50 teev.
Dab tsi yog qhov sib txawv ntawm DC01 thiab DC03 steel? DC01 - Cov qib no tuaj yeem siv rau kev ua haujlwm yooj yim, piv txwv li khoov, embossing, beading thiab kos duab. DC03 - Qhov kev kawm no yog qhov tsim nyog rau kev tsim kev xav tau xws li kev sib nqus thiab cov khoom sib sib sib zog nqus thiab muaj cov khoom siv nyuaj.
DC01 AM? Nws yog ib qho tsis-alloy txias-rolled steel nrog cov ntsiab lus muaj roj carbon tsawg heev. Nws feem ntau siv nyob rau hauv kev lag luam tsheb thiab ua kom cov tshuab hluav taws xob. Cov ntsiab lus muaj roj carbon tsawg ntawm cov hlau no ua rau nws yooj yim heev rau kev ua haujlwm nrog.
DC01 txhais li cas? DC01 sawv cev rau qib theem pib ntawm DC steel tsev neeg thiab tseem tau paub nyob rau hauv cov txheej txheem qub st12 lossis FEP01. Cov qib no tuaj yeem siv rau txoj kev ua haujlwm yooj yim xws li dabtsi yog khoov, coining, hlaws thiab kos duab.
DC03 qib steel yog dab tsi? DC03 yog cov hlau roj carbon hlau tsawg tus yam ntxwv los ntawm kev muaj kev kho kom zoo tshaj plaws. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm DC03 yog qhov tseeb tau txhais los xyuas kom meej tias cov khoom muaj cov neeg kho tshuab uas xav tau. Feem ntau, DC03 muaj qhov siab tshaj plaws ntawm 0.10% carbon, qhov ntau ntawm 0.45% manganese thiab kab ntawm phosphorus thiab leej faj.
