Txias Rolled Steel Qib DC04
Qhov tshwj xeeb sib sib zog nqus-kos qib DC04 tau teev tseg raws li tus qauv DIN EN 10130, uas tsom rau cov khoom txias- dov ca ua los ntawm cov hlau mos rau kev sib sau txias. Cov txheej txheem no qhia txog cov kev xav tau thiab kev sim cov txheej txheem rau txias -cov khoom dov uas yog ib qho tseem ceeb hauv ntau daim ntawv thov kev lag luam, tshwj xeeb tshaj yog qhov yuav tsum tau ua kom muaj qhov siab thiab zoo heev.
DC04 yog ib qho qis - carbon steel uas zoo siab nrog nws qhov tshwj xeeb txias formability. Cov tshuaj muaj pes tsawg leeg ntawm DC04 yog qhov sib npaug los xyuas kom meej tias cov khoom muaj qhov xav tau cov khoom siv kho tshuab. Cov ntsiab lus carbon hauv DC04 feem ntau yog qhov siab tshaj plaws ntawm 0.08%, thaum cov ntsiab lus manganese yog qhov siab tshaj plaws ntawm 0.40%. Qhov no muaj pes tsawg leeg txhawb lub siab formability thiab weldability ntawm cov hlau, ua rau nws zoo tagnrho rau kev thov kev tsim cov txheej txheem.
Cov khoom siv kho tshuab ntawm DC04 yog tus cwj pwm los ntawm lub zog qis ntawm qhov siab tshaj 210 MPa thiab lub zog tensile ntawm 270 thiab 350 MPa. Tshwj xeeb tshaj yog tsim nyog yog qhov siab elongation ntawm kev tawg yam tsawg 38%, uas qhia txog qhov zoo heev formability ntawm cov khoom. Cov khoom no ua rau DC04 qhov kev xaiv zoo tshaj plaws rau kev tsim cov khoom sib txuas uas yuav tsum tau muaj kev ua haujlwm siab thiab qhov zoo, xws li cov khoom siv lub cev hauv tsheb hauv kev lag luam tsheb lossis filigree qhov chaw hauv kev lag luam hluav taws xob.
