| Abstract: | A low carbon Bainitic steel XDB685[≤0.09C,1.20～1.60Mn,0.015～0.055Nb,0.008～0.030Ti, 0.2~0.6(Cr+N+Mo+B)] has devebped by using TMCP(Themomechanical Controlecd Pnsess)- RPC(Rdlaxed Pncess Contal)"-T(Tempering)technology. Test esulls showed thet the yidld strengh of40～60 mm steel plate was ≥600 MPa,the tensile strengih was ≥700 MPa, the impact energy at -40℃ was about 200 J,and the steel plate had excellent weldability. |
