Experimental study was carried out for improving strength and toughness of non-quenched and tempered casing tube N80. The results show that strength and impact toughness can be improved by adopting appropriate controlled cooling process after rolling or increasing cumulative deformation in the austenitic non-recrystallization zone,and better performance can be achieved with the combination of these two methods. The commercial production proves that the strength and impact toughness of the products so produced can be noticeably enhanced.
