Q: SPCC yog dab tsi?
A: SPCC stands rau Steel Phaj Cold Commercial, Japanese JIS tus qauv rau txias -rolled carbon steel nplooj ntawv thiab strips. Nws muaj cov pa roj carbon tsawg, muaj qhov du, thiab zoo formability. Tshwj tsis yog tias tau teev tseg, nws yog annealed + smoothed (S), nrog ci / matte tiav kev xaiv muaj.
Q: Dab tsi yog cov lus hauv SPCC (piv txwv li, SPCC-S-B) sawv cev?
A: S=Annealed + smoothed; 1/8 nyuaj (8), 1/4 nyuaj (4), 1/2 nyuaj (2), nyuaj (1); B=ci tiav, D=matte tiav; T=tus nqi ntsuas tensile yuav tsum tau (SPCCT).
Q: Dab tsi yog cov thicknesses ntawm SPCC?
A: Lub ntsiab thicknesses yog 0.5/0.8/1.0/1.2/1.6/2.0/2.3/3.2mm. Txias- dov txheem thicknesses yog ≤3.2 hli, thiab cov tuab tuab yog feem ntau SPHC kub- dov.
Q: Ua li cas SPCC cuam tshuam rau cov qib hauv tsev? A: DC01 thiab Q195/Q215 txias- cov ntawv dov, zoo ib yam li GB / T 11253, muaj cov khoom sib xws thiab cov khoom siv kho tshuab thiab tuaj yeem hloov tau rau ib leeg raws li cov neeg siv khoom.
Q: Yuav ua li cas yog qhov ceev thiab theoretical hnyav ntawm SPCC xam?
A: Ceev 7.85 g / cm³; Theoretical hnyav (kg)=Thickness (mm) × Dav (m) × Length (m) × 7.85.
