Hot Rolled Picking Steel

Hanxi - Hot Rolled Pickling Steel Exporter

Hot rolled pickling steel is steel that has been descaled of an oxide film and oiled to help fight corrosion. During the pickling process, hot rolled steel is descaled in a hydrochloric acid bath. The scale-free surface benefits forming, bending, stamping, and painting both in production savings and the quality of the finished part. The pickling process produces hot rolled steel that is durable and has improved formability while providing a cleaner surface for painting with a limited barrier to rust formation. 

Hanxi Steel performs batch pickling of hot rolled carbon steel products of many different types. We can pickle flat bar, angles, tubing and plate material and some specialty parts. Learn more

Process of Hot Rolled Pickling Steel Exporter

• Loading: Each rack is carefully loaded by separating individual pieces of material in rows on the rack. Each row is separated with angles in insure that our solution will reach every square inch of material

• Cleaning: The rack is then placed in a highly alkaline (sodium hydroxide based) cleaner in order to remove soils and oil from the surface of the metal.

• Rinsing the rack of steel is then thoroughly rinsed in two tanks to remove the cleaner from the material and to reduce the P-H before pickling.

• Pickling: The rack is then immersed in hydrochloric acid (HCI) for as long as it takes to remove the scale, rust and corrosion from the surface of the product.

• Rinsing: The rack is then rinsed in two tanks to remove the hydrochloric acid from the surface of the material.

• Cleaning: The rack is placed back into the alkaline cleaner in order to completely neutralize any acid residue that may remain on the surface of the steel.

• Final Rinsing: Our final rinse tank removes the cleaner from the material surface.
