Yog DC01 tib yam li CR4? Mob taub hau txias
Ntawm no thaum John Tainton, peb cov khoom lag luam DC01 Cov hlau me (feem ntau hu ua CR4), hauv kev sib txawv ntawm 0.9mm txog 3 hli.
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 steel?
DC01 Cov hlau carbon yog ib qho hlau sib sib zog nqus nrog cov khoom muaj zog siab. Tsis-hardening, nws cov ntsiab lus carbon tsawg heev ua rau nws yooj yim heev rau kev ua haujlwm thiab ductile, yooj yim rau deform. Nws yog qhov zoo tagnrho rau kev ua neeg sib tsoo los ntawm cov ntawv hlau muab tais.
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.
