The resent application and progress of non-quenched and tempered steel is re-viewed. The mechanism of strength and toughness and the method to improve them are dis-cussed. Some new research processes are presented,which include strengthening equation,solid solubility product equation of micro alloying elements,strengthening by intragranular ferrite (IGF),controlled rolling and cooling technology of non-quenched and tempered steel. The typi-cal applications of various non-quenched and tempered steels in automotive industry are 1isted. The problems for the production and application of non-quenched and tempered steel in China are also analyzed. Some suggestions for enlarging future manufacture and applications in auto-motive industry are also put forward.
