Abstract: Based on orthogonal experiment, the effects of Mn content, finish rolling temperature (FRT) and coiling temperature (CT) on mechanical properties of low-carbon steel were investigated by TMCP (thermo-mechanical control processing), and the mechanical properties were examined by variance analysis. The results showed that Mn content affects obviously the strength and plasticity, while CT affects significantly the yield strength which can exceed 400 MPa with other mechanical properties also improved well by readjusting FRT and CT if the Mn content in tested steel is 1.22% as mass fraction.
