Dab tsi yog cov tshuaj muaj pes tsawg leeg rau DC06?
Nws cov yam ntxwv muaj xws li cov pa roj carbon tsawg (C Tsawg dua lossis sib npaug li 0.008%, lossis qis dua), tsis tshua muaj manganese, phosphorus, thiab sulfur, thiab qee qhov ntawm txhuas (Alt Ntau dua lossis sib npaug rau 0.015%). Cov ntsiab lus tsis tshua muaj cov pa roj carbon monoxide yog qhov tseem ceeb kom ntseeg tau tias nws zoo heev stamping kev ua haujlwm.
Dab tsi yog cov cuab yeej cuab tam ntawm DC06?
Siv lub thickness ntawm 0.5 ~ 0.7mm ua piv txwv:
Tawm lub zog: 110 ~ 170 MPa
Tensile zog: Ntau dua los yog sib npaug rau 260 ~ 270 MPa
Elongation tom qab tawg: Ntau dua lossis sib npaug li 39% (qee qhov kev xav tau tuaj yeem ncav cuag Ntau dua lossis sib npaug li 41%, thiab txawm tias Loj dua lossis sib npaug li 45% los ntawm kev ua kom zoo dua)
Plastic strain ratio r90 tus nqi: Ntau dua lossis sib npaug rau 2.1 (thickness 0.5 ~<1.0mm)
Ua haujlwm hardening Performance index n90 tus nqi: Ntau dua lossis sib npaug rau 0.22 (thickness 0.5 ~<1.0mm)
Vim li cas qhov elongation ntawm DC06 tseem ceeb?
Ntau dua elongation qhia tias muaj zog yas deformation muaj peev xwm ntawm cov khoom, cia nws tiv taus ntau dua deformation thaum stamping yam tsis muaj cracking. Piv txwv li, thaum cov neeg siv siab xav tau, elongation tuaj yeem ncav cuag ntau dua lossis sib npaug li 45%.
r-tus nqi thiab n- tus nqi ntawm DC06 yog dab tsi?
r-tus nqi (plastic strain ratio): Ntsuas cov ntawv tsis kam rau thinning. Qhov siab dua r-tus nqi qhia tau tias qhov sib sib zog nqus zoo dua - kos duab.
n-tus nqi (ua haujlwm hardening Performance index): qhia txog cov khoom muaj peev xwm ua kom muaj zog thaum lub sij hawm yas deformation. Qhov ntau dua n- tus nqi qhia tau tias muaj zog tiv thaiv rau hauv zos concentrated deformation, uas muaj txiaj ntsig zoo rau kev ua kom tsis sib xws.
Puas yog DC06 muaj teeb meem kev laus?
Raws li IF steel, DC06 tsis muaj kev phom sij rau kev laus; nws cov khoom tsis hloov pauv nrog lub sijhawm khaws cia.
