Facts About Steel Pickling

Iron oxide formation results in a layer of flaky scale that significantly reduces the quality and performance of the metal.

What is Steel Pickling?

Steel pickling is a metal decontamination process involving acid bathing science. Hot worked steel is dipped into a substance known as pickle liquor, hence the name, to remove all surface impurities that can increase the rate of iron oxide scale, rust, and similar metal corrosion. Pickle liquor can be either sulfuric acid or hydrochloric acid. Both substances render equivalent efficacy.

Conventional hot worked steel can be decontaminated with so for occur hydrochloric acid bathing, but any steel material with the carbon content higher than 6% will require an additional dipping into an acid bath of nitric, phosphoric, or hydrofluoric acid. Following the acid bath process, treated steel is rinsed clean with water and ready for further treating. Typically, cold working is the next step following steel pickling.

Smooth Clean Surface (SPS) and Flame Cleaning

Smooth clean surface (SPS) is a common alternative to steel pickling that remove surface impurities by pushing sheet-metal through a series of rollers and mechanical abrasives. It is often chosen in place of steel pickling when dipping is structurally incompatible, or the particular type of metal or impending application is vulnerable to acid bathing. Another common alternative to steel pickling is known as flame cleaning. This steel decontamination process uses an oxyacetylene flame that essentially burns off all surface impurities.
