The specific heat capacity of steel is 452 Joules per kilogram Kelvin, or 0.108 calories per gram Kelvin. This value is based on room temperature and atmospheric pressure. Specific heat capacity is defined as the heat energy needed to raise the temperature of one kilogram of a material by 1 degree Kelvin.
The amount of heat a material needs to change its temperature depends on the material's mass, the type of the material and the change of temperature that will occur, either positive or negative. The heat energy of a material can be calculated using the material's specific heat capacity from multiplying the material's mass by its specific heat capacity and its temperature change.
