摘要
The invention relates to a low-carbon bainitic steel grade with high yield strength and high yield ratio for application in seismic-proof buildings. The chemical composition of the starting material in wt% is c = 0.05, Mn = 3, S = 0.02, P = 0.02, Si = 0.02, Al = 0.01, Mo = 0.06, Ti = 0.01, Nb = 0.01, and B = 0.006, and in that mechanical properties of the produced steel comprise yield strength = 670 MPa, ultimate tensile strength = 710 MPa, elongation = 15%, and yield ratio = 0.9.
