The steel contamination problem comes from nuclear bomb tests, not just the refining of radioactive materials. So long as no one nukes the moon, we're fine.

Plus, the contamination occurs from the air used when the steel is made, so unless you can find a way to run a blast furnace in a vacuum there's no way to make uncontaminated steel even if you brought iron ore from the moon
