DX51D + Z100 steel sawb txhais li cas?
DX51D + Z100 yog ib qho kev xaiv rau kub -dip galvanized steel sawb. "DX51D" yog lub hauv paus phaj tsim, "D" sawv cev rau txias- ua cov hlau tiaj tus, thiab nws daim ntawv thov tseem ceeb yog ua kom tau raws li qhov yuav tsum tau ua kom txias. "X" qhia tias lub hauv paus phaj dov txheej txheem tsis tau teev tseg, tso cai rau cov tuam txhab xaiv cov txheej txheem dov uas tsim nyog raws li kev ua kom zoo dua. "51" yog cov hlau qib serial tooj, sib xws rau ib qho tshwj xeeb ntawm cov khoom siv kho tshuab. "Z100" sawv cev rau hom zinc txheej ntshiab, "Z" yog lub npe rau cov zinc txheej ntshiab, thiab "100" qhia tias qhov hnyav zinc txheej tsawg kawg nkaus ntawm 100g ib square meter ntawm cov hlau sawb (ntawm ob sab ua ke). Qhov hnyav txheej txheej no yog qhov taw qhia tseem ceeb ntawm steel sawb txoj kev tiv thaiv corrosion.
Dab tsi yog cov qauv rau DX51D + Z100 steel sawb?
Tam sim no, kev lag luam feem ntau ua raws li cov qauv thoob ntiaj teb, qib siab thoob ntiaj teb cov qauv, thiab cov qauv tsim hauv tsev. Cov txheej txheem thoob ntiaj teb thiab txawv teb chaws suav nrog Europe's EN 10142 (kub-dip galvanized tiaj tus hlau cov khoom lag luam rau txias sib sau), EN 10147 (kub tsis tu ncua-dip galvanized me me steel tiaj tus khoom), EN 10292 (kub-dip galvanized steel los xij), Nyiv '02 cov hom phiaj JIS (kub-dip galvanized steel los xij thiab strips), thiab US's ASTM A653 / A653M (kub-dip galvanized structural steel los xij). Cov qauv hauv tsev suav nrog BQB 420 (Baosteel tus qauv kev lag luam, muaj feem xyuam rau kev tsim khoom sab hauv thiab kev tshuaj xyuas zoo). Cov qauv no qhia meej meej cov cim tseem ceeb ntawm steel sawb, suav nrog tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab txheej txheej zoo.
Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm DX51D + Z100 steel sawb?
Nws cov tshuaj muaj pes tsawg leeg nruj me ntsis ua raws li cov qauv kev coj ua, nrog rau cov ntsiab lus tseem ceeb tswj raws li hauv qab no: Carbon (C) Tsawg dua lossis sib npaug li 0.18%. Cov ntsiab lus carbon tsawg ua kom zoo weldability thiab txias tsim cov khoom ntawm steel sawb, tsis txhob tawg thaum ua haujlwm vim yog cov ntsiab lus carbon ntau dhau. Silicon (Si) Tsawg dua lossis sib npaug li 0.50%. Silicon txhim kho lub zog ntawm cov hlau sawb, tab sis cov nyiaj ntau dhau tuaj yeem cuam tshuam qhov adhesion ntawm galvanized txheej, yog li cov kev txwv sab saud yuav tsum tau tswj nruj me ntsis. Manganese (Mn) Tsawg dua lossis sib npaug li 1.20%. Manganese tuaj yeem ua kom lub zog tensile ntawm steel sawb los ntawm kev daws teeb meem ntxiv zog yam tsis muaj kev txo qis nws cov plasticity. Phosphorus (P) Tsawg dua lossis sib npaug li 0.12%, thiab sulfur (S) Tsawg dua lossis sib npaug li 0.045%. Phosphorus thiab sulfur yog cov teeb meem impurities. Cov nyiaj ntau dhau tuaj yeem ua rau txias thiab kub brittleness hauv steel sawb, cuam tshuam rau kev ua haujlwm thiab kev nyab xeeb, yog li lawv cov ntsiab lus yuav tsum nruj me ntsis txwv.
Dab tsi yog cov yam ntxwv ntawm DX51D + Z100 steel sawb?
Mechanical zog sib txawv raws qib steel. CQ qib (qib kev lag luam feem ntau) muaj lub zog tensile ntawm 270-500 MPa thiab lub zog tawm ntawm 140-300 MPa. Qib DQ (qib sib sib zog nqus nqus) muaj lub zog tensile zoo sib xws rau qib CQ, tab sis lub zog ruaj khov dua thiab zoo dua formability. Nyob rau hauv cov nqe lus ntawm elongation, CQ qib steel sawb muaj ib tug elongation ntawm ntau tshaj los yog sib npaug rau 22% rau thicknesses<0.7mm, while DQ grade has an elongation of ≥24% for the same thickness. This excellent elongation ensures the steel strip is suitable for various cold working processes such as bending and stamping, and is less susceptible to breakage during processing.
Dab tsi yog qhov thickness ntau rau DX51D + Z100 steel sawb?
Cov pa ntau lawm thickness ntau yog 0.12-3mm, uas feem ntau npog cov ntawv thov kev lag luam feem ntau. Ntawm lawv, nyias- ntsuas steel strips ntawm 0.12-0.5mm feem ntau yog siv rau hauv cov xwm txheej uas yuav tsum tau muaj siab ntawm qhov hnyav thiab qhov tseeb, xws li cov khoom siv hauv tsev thiab cov khoom siv hluav taws xob; nruab nrab-gauge steel strips ntawm 0.5-2mm yog dav siv nyob rau hauv lub tsev keels thiab automotive sab hauv qhov chaw; tuab-gauge steel strips ntawm 2-3mm yog haum rau cov teb uas xav tau ntau dua ntawm lub zog, xws li cov khoom siv kho tshuab thiab cov thawv ntim khoom. Qee cov tuam ntxhab tuaj yeem kho cov khoom siv nrog cov tuab tshaj li cov pa ntau raws li cov neeg siv khoom tshwj xeeb xav tau.
