1.Txoj lus hauv cov khoom siv tshuab?
Paib lub zog:
DX52D cov txiaj ntsig lub zog yog feem ntau yog ntawm 140-280 MPa;
DX53D cov txiaj ntsig lub zog yog qis dua, feem ntau nyob rau hauv 120-240 MPa ntau, thiab cov khoom pov thawj zoo dua.
Lub zog tensile:
DX52D lub tensile yog 270-410 mpa;
DX53D lub tensile lub zog yog qis dua qis dua, ntawm 270-380 MPa, ua rau nws haum ntau rau cov txheej txheem uas yuav tsum muaj kev deformation ntau dua.
Elongation:
Ob cov ntaub ntawv pom tau tias muaj tsawg kawg 28% (rau thicknesses tsawg dua los yog sib npaug rau 1.0 hli). Txawm li cas los xij, DX53D cov qis dua cov txiaj ntsig zoo hauv kev ua haujlwm zoo dua thaum lub sij hawm tiag tiag.
2.What yog qhov sib txawv ntawm kev ua haujlwm?
Muaj peev xwm:
DX52D yog ib qho dav dav {{1} Txoj kev sib sau cov ntaub ntawv galvanized rau haum, stamping, thiab lwm yam khoom noj (piv txwv li cov txheej txheem tiaj).
DX53D yog qhov tob tob-}}}}}}- kev ua yeeb yam thiab kev laus tsis kam. Nws tuaj yeem tiv taus ntau txoj kev ua tiav cov txheej txheem (piv txwv li, kev sib sib zog nqus duab thiab loj {{Nplooj ntawv siab li cas) yam tsis muaj kev tawg.
Kev laus rhiab:
DX53D undergoes ib qho kev kawm analing ntau dua, ua rau muaj kev sib tw qis dua (piv txwv li qhov kev siv tau ruaj khov.
3.Qhov dab tsi yog qhov sib txawv hauv cov xwm txheej thov?
DX52D: feem ntau siv nyob rau hauv cov ntawv thov uas yuav tsum tau ua tiav (piv txwv li cov vaj tsev vov tsev), thiab cov tshuab ntxhua khaub ncaws (piv txwv li, chassis nkhaus).
DX53D: feem ntau siv nyob rau hauv cov ntawv thov kev lag luam sib sib nqus (piv txwv li, cov vaj tse tank), nrog rau cov vaj tse ua roj. Nws yog qhov tshwj xeeb zoo -} haum rau cov khoom lag luam nrog cov duab nyuaj thiab qhov tseem ceeb deformation.
4.Qhov dab tsi yog qhov tseem ceeb ntawm ob qho?
Cov tub ntxhais sib txawv nyob rau hauv kev tsim kev ua tau zoo: DX53D muaj cov peev xwm tshaj tawm thiab yooj yim} {{{5, {{5, yuan ib tev). Qhov kev xaiv yuav tsum yog ua raws cov kev nyuaj ntawm cov txheej txheem {{}} rau cov kev xaiv yooj yim, thaum muaj kev sib sib zog nqus cov ntawv thov DX53D.
5.Qhov yog lub corrosion tsis kam ntawm galvanized steel los xij DX52D thiab DX53D?
Lub corrosion resistance ntawm galvanized steel los xij DX52D thiab DX53D yog feem ntau txiav txim siab los ntawm cov yam ntxwv ntawm lawv cov txheej zinc. Tsis muaj qhov tseem ceeb hauv kev corrosion tsis kam ntawm ob, tab sis cov kev ua tau tshwj xeeb yuav raug cuam tshuam los ntawm cov tuab ntawm zinc txheej thiab kev kho kom nto.
