Q235/S235jr/S355jr/S235/A36/Dx51d/Dx52D/Dx53D/SGCC Strong Gi Galvanized Phaj rau Automotive

DX53D yog dab tsi?
DX53D yog kub-dip galvanized steel ntawv uas ua raws li DIN EN 10346, nrog rau cov khoom siv tooj 1.0951. Nws yog cov hlau me me thiab sib sib zog nqus- qib kos duab.
Dab tsi yog "DX" hauv DX53D sawv rau?
"DX" yog cov lus ua ntej siv hauv German cov qauv rau kub -dip galvanized steel ntawv rau txias txias.
Dab tsi yog qhov txawv ntawm DX53D thiab DC53D?
DC53D yuav tsum ua raws li qhov txias txias -rolled sheet substrate, uas ua rau lub ntsej muag huv si, ci ntsa iab thiab tsim nyog rau cov ntawv thov uas yuav tsum tau ua kom zoo thiab tsim tau. DX53D tuaj yeem ua raws li kub- dov lossis txias- dov daim ntawv thiab tsim nyog rau kev dav dav - lub hom phiaj tsim.
Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm DX53D daim ntawv?
Cov tshuaj muaj pes tsawg leeg (qhov siab tshaj plaws feem ntau) yog: C Tsawg dua lossis sib npaug li 0.12%, Si Less dua lossis sib npaug li 0.50%, Mn Tsawg dua lossis sib npaug 0.60%, P Tsawg dua lossis sib npaug 0.10%, S Tsawg dua lossis sib npaug li 0.045%, thiab Ti Tsawg dua lossis sib npaug 0.30%. Cov yam ntxwv ua haujlwm
Dab tsi yog cov yam ntxwv ntawm DX53D daim ntawv?
Lub zog tawm los yog 140-260 MPa, lub zog tensile yog 270-380 MPa, thiab elongation tom qab tawg (A80) yog ntau dua lossis sib npaug li 30%.
