  • MICRO-MOLYBDENUM-TYPE WEATHERING BRIDGE STEEL PLATE AND PREPARATION METHOD THEREOF
    Publication number: 20240158880
    Abstract: A micro-molybdenum-type weathering bridge steel plate disclosed by the present invention is characterized in that the steel plate is smelted from the following components by weight: C: 0.05-0.08%, Si: 0.30-0.50%, Mn: 1.25-1.35%, P: 0.010-0.014%, S?0.003%, Nb: 0.020-0.030%, Ti: 0.010-0.020%, V: 0.040-0.050%, Cu: 0.25-0.40%, Ni: 0.25-0.35%, Cr: 0.45-0.55%, Mo: 0.03-0.08%, Alt: 0.020-0.040%, and the balance from Fe and impurities. Less content of molybdenum reduces the production cost of the steel plate, the yield strength of the steel plate is 500-600 MPa, the yield strength ratio is ?0.85, and the maximum thickness of the steel plate can reach 80 mm.
