DC03 - Kub dov hlau
DC03 yog ib qho qis - carbon hlau uas muaj qhov ua tau zoo heev. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm DC03 yog txhais tau meej los xyuas kom meej tias cov khoom muaj cov khoom siv kho tshuab uas xav tau. Feem ntau, DC03 muaj qhov siab tshaj plaws ntawm 0.10% carbon, qhov siab tshaj plaws ntawm 0.45% manganese thiab kab ntawm phosphorus thiab sulfur. Qhov me me ntawm cov ntsiab lus alloying no pab txhawb rau qhov zoo formability thiab weldability ntawm cov hlau.
Cov cuab yeej cuab tam ntawm DC03 kuj tau hais meej meej. Cov khoom muaj lub zog tawm los ntawm yam tsawg kawg 140 MPa thiab lub zog tensile ntawm 270 thiab 370 MPa. Tsis tas li ntawd, DC03 muaj qhov elongation ntawm qhov tawg ntawm yam tsawg kawg 34%, uas qhia txog nws cov formability zoo heev. Cov khoom no ua rau DC03 tshwj xeeb tshaj yog tsim nyog rau kev tsim cov khoom sib txuas uas yuav tsum tau muaj kev ua haujlwm siab thiab zoo, xws li lub cev hauv kev lag luam tsheb lossis khoom siv hauv tsev.
DIN EN 10130 tus qauv kuj tseem qhia txog qhov kam rau ua rau qhov ntev, cov duab thiab qhov chaw tiav. Cov kev tolerances no yog ib qho tseem ceeb los xyuas kom meej cov khoom zoo tsis tu ncua thiab ua kom tau raws li cov neeg siv khoom kawg. Qhov saum npoo ntawm cov khaub thuas- dov ca cov khoom tuaj yeem muab rau hauv ntau yam zoo, los ntawm matt mus rau glossy, kom ua tau raws li cov kev cai tshwj xeeb ntawm kev siv sib txawv.
