My grandfather worked in a machine shop over 30 years ago. Even back then they worked mostly with imported product. According to him, the US steel was very low quality - aimed at industries that needed such huge amounts of it that shipping was expensive and quality wasn't an issue.
If that is still the case, then demand for US steel is determined by infrastructure investment, not trade.
