The present work is about the effect of austenitizing temperature on the bainitic ferrite transformation during hot induction bending of line pipe steel of grade API X65 PSL-2. The essential characteristics of the pipeline were first manufacturing by hot rolling the plates by thermo-mechanical control process(TMCP) and after followed by the pipe making process by JCOE forming route and finally the line pipe subjected to the hot bending process. During hot bending the line pipe exposed to localized induction heating followed by water cooling. Bend portion of the pipe examination carried with respect to microstructure and mechanical properties normally strength, toughness, and hardness. The results showed that significant microstructural changes observed by varying austenitizing temperature, at a high austenitizing temperature of range between 950-990°C the resulting microstructure found very fine bainitic ferrite & ferrite well exists intragranular in prior austenitic grain(PAG) pockets. The hot bend pipe of the resulting microstructure greatly improved the strength and toughness of the line pipe steel.
