Effect of temperature and composition on thermal properties of carbon steel

To simulate steel continuous process (such as induction heating of steel wire) accurately, the relevant thermal properties of carbon steel (within 0.06 to 1.22 wt. % of carbon) were determined as a function of temperature and carbon contents by multiple regression analysis method in this paper. These properties included the thermal conductivity, specific heat, and coefficient of linear thermal expansion, which are discussed within the temperature range from 0°C to 800°C. The effect of composition on thermal conductivity, specific heat, and coefficient of linear thermal expansion is investigated respectively. The results indicate that it is carbon content, instead of other compositions, has a significant influence on the thermal properties of carbon steel. In addition, the effects of carbon content of steels on the thermal properties of carbon steels with different temperature sensitivity in the range 0°C to 800°C have been presented.
