Global warming and air pollution by human made gases such as CO2, is mainly produced by automotive industry that results in great risk for human health. The aim of this study is to reduce the above problem by using the high strength materials with low density in the manufacturing of automotive vehicles. An approach applied here is to enhance the strength by reducing the grain size, lowering the density and increasing elongation. Four steel samples with different chemical compositions were selected. Samples were heat treated from 850 °C to 1250 °C and cooled in water. Grain size distribution was calculated using matrox inspector software and result was plotted using origin. It was found that 850 °C has lowest and 1250 °C has highest grain sizes. Strength of steel can be increased not only by adding the alloying elements but also by controlling grain size. Light weight material consumes lower fuel and emits lower CO2, thus it minimizes the global warming and air pollution.
