Q420 round bar tseem hu ua low alloy high -lub zog steel, thiab nws cov tshuaj muaj pes tsawg leeg muaj ib qho me me ntawm alloying ntsiab los txhim kho nws lub zog, ductility thiab corrosion kuj. Tsis tas li ntawd, Q420 round bar muaj qhov txias txias, vuam thiab kev kho cua sov. Q420 round bar yog dav siv nyob rau hauv qee daim ntawv thov uas yuav tsum tau thauj khoom -cov kabmob hnyav.Q420 round bar muaj lub zog ntau dua thaum nws cov tawv tawv kuj tseem ceeb dua. Thaum raug rau sab nraud quab yuam, nws muaj peev xwm tswj tau lub peev xwm deformation zoo dua, yog li ua kom qeeb ntawm kev tawg.Q420 puag ncig bar muaj qee yam alloying cov ntsiab lus hauv cov tshuaj muaj pes tsawg leeg, kom nws muaj kev tiv thaiv corrosion zoo dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav, qhov tshwj xeeb no tseem ceeb dua.
