Hot-rolled steels often have mill scale that needs to be removed. Once pickling removes the mill scale, the steel is very susceptible to flash rusting because of its exposed surface. Oiling after pickling prevents this. If there are a high amount of alloying elements in the steel alloy, then more complex pickling processes will need to be used or
