From the iron carbon phase diagram published by Benz and Elliott, it has shown the solid lines are carbon lines which indicate activity of carbon with respect to graphite in standard state is 1.

See lessActivity of any solid is 1.0, in this case carbon is solid so activity will be 1. And activity of liquid steel will be different.
