Two kinds of Mn-Si-Mo low carbon steels were designed to study the effects of Mn on the microstructures and properties of hot rolled low carbon bainitic steels. To reduce the production cost, a very low Mo content of 0.13% was added in both steels. After hot rolling, the mechanical properties of samples were tested. Microstructure was observed and analyzed by optical microscope and transmission electron microscope. The results show that the strength of tested steels increases with the increase in Mn content, while the elongation decreases. When Mn content increases, the bainite microstructure increases. The results can provide a theoretical basis for composition design and industrial production of low cost low carbon bainitic steels.
