What Is Steel Pickling? National Material Company

During hot working processes,an oxide layer (referred to as scale,due to the scaly nature of its appearance) develops on the surface of the metal.Before most cold rolling processes,previously hot rolled steel goes through a pickling line to remove the scale from the surface and make it easier to work.U001en Hot-Rolled Steel Sheets and CoilsOur Hot-Rolled Steel Sheets and Coils are applied to a wide range of applications such as,automobiles,electrical appliances,construction materials,containers,and steel pipes,and receive high acclaim from our customers for its excellent quality. surface finish to the steel.In the pickling line,surfaceSurface preparation - SteelConstructionfoInitial surface condition.Structural steel elements in new structures are usually either hot rolled sections or fabricated plate girders.The initial steel surfaces normally comply with rust grades A or B according to BS EN ISO 8501-1.Material that is pitted,i.e.rust grades C or D,should be avoided if possible,since it is difficult to clean all the corrosion products from the pits during
