Thermal Expansion of Materials (Inches/100 Feet)

The tabulated values have been calculated based on the change in temperature from 70°F to the listed value measured in inches/100 feet. These values are for evaluating thermal expansion only. They are not an indication that a material is suitable for service at the listed temperature.
