| Abstract: | In this paper recrystallization of deformed austenite during hot deformationand phase transformation during subsequent cooling of high toughness pipeline steel havebeen investigated. The reasonable technologies of controlled rolling and controlled cooling fortest steel have been optimized. Using this technology, the toughness value of the X60-X65pipeline steel plate produced by Baosteel is one time more than that of the plates producedbefore. The comprehensive property of this plate reaches or exceeds that of the imported steelfrom Japan. |
