摘要
研究了珠钢CSP生产0．015％～0．045％Nb微合金钢的显微组织和力学性能。分析结果表明：钢板的组织以铁素体为主，同时存在少量的珠光体组织；通过对钢板进行拉伸试验和冲击试验可知钢板具有优良的强韧性能，可满足管线钢和汽车用钢要求。
Microstructure and properties of Nb microalloyed steel produced by zhujiang CSP process were analyzed. The results showed that the microstructure consists ferrite and small amout of pearlite. The steel has excellent obdurability by tensile test and impact test, and it met the requirement of pipeline and automobile users.
