摘要

The fundamental research and industry trials of the third generation automobile steel QP980 were introduced in this paper,including chemical ingredient,mechanical properties,microstructure,forming limit and basic performance parameters.The application of QP steel of the B-pillar was researched,and the QP980,DP600 and hot forming steel were compared in the aspect of formability,safety and cost.The results showed that the QP980 replacing DP600 steel single piece can reduce the weight by 2.4 kg.The security and performance is basically the same as that of hot forming steel using 22MnB5,and the cost is reduced by 30%.
