The specific type of steel and its composition determine the average thermal expansion coefficient of steel sheets. Nonetheless, a widely accepted approximation for the thermal expansion coefficient of steel sheets is approximately 12 x 10^-6 per degree Celsius (12 parts per million per degree Celsius). It is pertinent to mention that this approximation may slightly deviate depending on the grade and composition of the steel utilized.
The average thermal expansion coefficient of steel sheets varies depending on the specific type of steel and its composition. However, a commonly accepted average value for the thermal expansion coefficient of steel sheets is around 12 x 10^-6 per degree Celsius (12 parts per million per degree Celsius). It is important to note that this value is an approximation and can vary slightly depending on the specific grade and composition of the steel being used.
The average thermal expansion coefficient of steel sheets is typically around 10-12 x 10^-6 per degree Celsius.
