RFQ Details

Hydrochloric acid is a strong inorganic acid that is used in many industrial processes such as refining metal. The application often determines the required product quality.[13]
Pickling of steel

One of the most important applications of hydrochloric acid is in the pickling of steel, to remove rust or iron oxide scale from iron or steel before subsequent processing, such as extrusion, rolling, galvanizing, and other techniques.[13][26] Technical quality HCl at typically 18% concentration is the most commonly used pickling agent for the pickling of carbon steel grades.
