Abstract��The strength of low-carbon bainitic steel made by a steel company was instability because it was not tempered for a limited production condition. After the analysis of metallographic examination, mechanical properties, macroscopic examination, SEM and energy spectrum, it showed that the strength was related to dimple size, microstructure and inclusions. Higher yield strength can be obtained when the dimple was large and deep; the strength is higher with lathy bainitic of large scale and smaller MA island; large size inclusions, especially oxides and sulfides containing Al and Ca is the weak leak and easy to break.

Key words�� strength tensile fracture microstructure inclusion
