Abstract The fact,that the yield strength of coldrolled, annealed, skinpassed strip produced from CSP hot coil is higher than expected is observed, which causes lower formability. Systematical research was done on recrystallization behavior, annealing and skinpass technology, coiling tension of TCM, hot rolling technology and chemical composition. Problems of high hardness and cracking during drawing were solved for CQ, DQ grade products.

Key words： CSP substrate coldrolled annealed skinpassed sheet steel yield strength
