steel will rub off onto the stainless steel surface as a film of unalloyed steel,and,after exposure to moisture in the atmosphere for a few days,that unalloyed steel film will form ugly rust.This happens because the unalloyed steel film on the stainless steel has little or no chromium,so the film transforms to ordinary “red rust”.Once the
