Abstract:
    The production process of SCP for automobile crossbeam includes the steps of converter smelting, LF refining, continuous casting and rolling, coiling and product inspection. The steel of SCP for automobile crossbeam consists of C 0.16-0.20 wt%, Si 0.3-0.5 wt%, Mn 1.3-1.5 wt%, P not more than 0.015 wt%, S not more than 0.010 wt%, Ti 0.01-0.03 wt%, Als 0.020-0.035 wt%, N not more than 65 PPm. Compared with available technology, the present invention has the advantages of relatively low alloy content in the steel, easy control of the chemical comprise, short production process and low production cost.
