As mentioned in previous posts, hot rolled steel is the most basic form of carbon steel. However, the scale that is left behind on hot rolled steel after it is formed is undesirable in many manufacturing applications and processes. In order to combat the scale issue, mills started to pickle and oil their steel to create a more desirable product for end users.
With competitive price and timely delivery, Hunter Special Steel Co., Ltd sincerely hope to be your supplier and partner.
Thus, hot rolled pickled and oiled (from here on referred to as HRPO) flat rolled steel coils were born. HRPO 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 of applying dried oil to the steel’s surface in order to prevent rusting. HRPO flat rolled steel is ideal for plate burning and plasma cutting processes in order to manufacture and machine smaller, more precise steel components and parts out of HRPO sheet and plate.

Hot rolled steel products will scale in contact with oxygen and water vapor after the rolling process.
Pickling is a metal surface cleaning process in which an acid bath (either sulfuric or hydrochloric) removes rust, stains, and unwanted contaminants that could interfere with subsequent fabrication processes like bending, forming, painting, and stamping.
After the pickling process, steel can oxidize after extended exposure to oxygen and atmospheric moisture. Finally, the oil film is applied to the steel to create a protective shield.
