Help calculate to what temperature a flange needs to be heated for its diameter to expand by 10 mm

Experts, please help calculate what temperature is required and for how long it needs to be heated to achieve this goal. I’m not sure if the software JMatPro, which is used for material property simulation and analysis, can be considered for this purpose. Since the flange is ring-shaped, it shouldn’t be possible to calculate it using linear expansion. The flange has an outer diameter of 3900 mm, an inner diameter of 3200 mm, and a thickness of 135 mm; it is made of carbon steel.
Approximately 312.5 degrees, with a linear expansion coefficient of 12X10^-6 C^-1. For reference only
312.5 degrees refers to the temperature difference
