What Is Hot Rolled Pickled and Oiled (HRPO) Steel

2016-03-21HRPO steel is still considered hot rolled steel even though it does not have any scale The final product of HRPO steel is created when steel mills use acid baths to remove the scale that usually forms on the surface of carbon steel coil as the coil is cooling Once the coil is bathed in acid it is "pickled" The pickling process consist
