Abstract

The precipitate in ULC-BH steels was analyzed by the phase analysis, the expressions for calculation of solution C content in the ULC-BH steel treated by Ti and Nb was developed. The test result indicates that the BH2 value was improved with the increasing of solution C content. The BH2 value can be improved by enhancing the temperature of annealing and cooling rate. The steel has higher BH2 value when the coiling temperature was 640 compared with 710 and the annealing temperature and cooling rate have more effect on bake hardening value than coiling temperature.
