No it was not pine, pine is too soft and not strong enough, I think it was probably tulip poplar, birch, maple, or some other grainless hardwood they used for mill work and structural wood. Ive had cabinets that also used ash or elm for structural parts, but they switched to white wood for the millwork as it did not need to be filled and cut cleanly. I've used birch to replace cabinet parts before though tulip poplar would work as well, tulip poplar is one of the harder species of poplar.
