Pickled and Oiled Steel

Pickled and Oiled Steel

The Short Iron Store a metal supplier, fabricator, and custom design company located just north of downtown Fort Worth. We offer stainless, carbon, aluminum, tool steel, and even specialty metals. If we don’t have it, we can special order nearly anything for you. One of the many metals we offer is pickled and oiled steel.

 

What is Pickled and Oiled Steel?

It all begins with hot rolled steel. The steel is fed into a furnace and heated to an extremely high temperature, around 1700 degrees Fahrenheit. Once it is hot and malleable, the steel is passed through rollers until it reaches its target thickness and form. After cooling, the steel is left with oxide scale on its surface. If this scale is not removed, it can affect the quality of the steel and keep surface treatments from adhering to it. Pickling and oiling is the procedure used to remove the oxide scale that comes from the steelmaking process.

 

The Pickling and Oiling Procedure

Pickling involves running the finished hot rolled steel through a diluted bath of hydrochloric or sulfuric acid. This bath is known as a “pickling bath”. This removes all of the scaling from the surface of the steel, but it also leaves the steel more porous and prone to rust. A protective oil layer is applied to counteract this effect.

Here is a step-by-step look at the pickling and oiling process:

  • Step 1: Loading. The steel is separated into individual pieces of material in rows on the rack. Each row is separated with angles to ensure that the pickling bath reaches every last bit of material.
  • Step 2: Cleaning. The loaded rack is then placed into a highly alkaline bath to prepare it for the acidic pickling process.
  • Step 3: Rinsing. The rack of steel is then rinsed in two tanks to remove the alkaline cleaner from the material and reduce the PH before pickling.
  • Step 4: Pickling. The rack is then submerged in a diluted bath of hydrochloric acid or sulfuric acid for as long as it takes to remove the oxide scale, rust and corrosion from the surface of the steel.
  • Step 5: Rinsing. The rack is rinsed again to get the acid off of the metal.
  • Step 6: Cleaning. The rack is once again submerged in the alkaline cleaner to neutralize any acid residue left on the steel.
  • Step 7: Final Rinse: All of the cleaning solution is rinsed away.
  • Step 8: Oiling: A protective coating of either water-soluble or mineral-based oil is applied to the steel to prevent rusting.

 

Caring for Pickled and Oiled Steel

Acid pickling is an important step in refining hot rolled steel, but it also leaves the metal more vulnerable to rust. Areas of high humidity are harmful to pickled steel, so be sure to store any non-oiled pickled steel in a dry place. If the steel has been oiled, it will have protection against water, rust and corrosion unless the oil layer is removed.
