Thermal diffusivity is a measure of the rate of thermal energy dissipation through materials. Its unit of measurement is in units of meter square per second, m2/s. The thermal diffusivity of ASTM A517/A517M A517 Grade F steel is in the range of 11.56 to 14.9 m2/s, depending on heat-treated conditions used to harden the steel. In an annealed form, it has a thermal diffusivity of about 11.56 m2/s. After heat-treating, it can increase to as high as 14.9 m2/s, thus increasing its overall thermal conductivity.
