| Abstract: | This paper deals with the microstructure and properties of multimicroalloying low carbon SiMn3 type bainitic steels that are suitable for home natural resources. under different heat treatment. The results show that this kind of steels are to have mainly bainitic structure at aircooling condition which have good strength and toughness, and the best combination of strength and toughness are obtained after low or/and medium tempering. However, a temper brittleness has appeared after high temper. |
