Synopsis : A deep drawable cold rolled steel sheet for enameling use was developed. The steel sheet was made from continuously cast Ti bearing steel with extremely low C content. Processing conditions of the steel sheet are discussed in this paper. Fishscaling is more effectively prevented by the use of TiN precipitates rather than TiC precipitates. TiN in steels less deteriorates press formability under any hot rolling condition that TiC. Smut deposited on the steel surface increases during pickling for enameling pretreatment with increasing Ti content in steel, resulting in poor enamel adhesion. The amount of Ti in steel must be restricted to less than 0.06% to obtain excellent enamel adhesion. Continuously annealing process is preferable for preventing cold-work embrittlement in the steel. |
