What is pickling steel?
Pickling is a metal surface cleaning process that is most commonly used after a metal is formed. Pickling cleans a metal surface by placing a metal into contact with an acid known as the pickling liquor. The type of acid that makes up the pickling liquor is dependent on the metal being pickled, but for most low alloy steels it is hydrochloric acid. For metals that are highly resistant to acids, a more powerful acid or a two-step pickling method may have to be used to achieve the desired cleaning results.
How is pickling performed?
Before a metal can be pickled, it is typically rinsed with a solution to remove large particles of dirt and debris. Following the rinsing stage, the metal is placed into a pickling liquor bath. Once the metal is immersed in the pickling liquor, the acid works to remove impurities from the surface. When a specified immersion time limit has been reached, the metal is removed to prevent overexposure to the acid. With the proper pickling liquor and the correct immersion time, the surface discontinuities will be removed from the metal surface with minimal metal loss. After being removed from the pickling liquor, the metal is rinsed again. Following this rinse, it often goes through a process known as oiling.
