Abstract��The reasons of non-yield and lower elongation of HRB400(Nb) steel bar were studied .The results showed that the main reason was high content of bainite in steel, high content of C��Mn and rapid cooling rate were main reasons of bainite forming.Non-yield of HRB400(Nb) was improved by controlling C��Mn content and cooling rate.
