0. 002 8 ~0.004 2N) have been studied and expressions for solution C content in test steel were established by quantitative phase analysis. Results showed that increasing calculated value of solution C content
the bake hardening BH

value increased; with increasing annealing temperature (810 ~ 850 °C ) of cold rolled plate
the BH

value increased ;and as annealed at 820 °C
the BH

value of plate coiled at 640 °C was higher than that coiled at 710 °C.
