C23G

CLEANING OR DE-GREASING OF METALLIC MATERIAL BY CHEMICAL METHODS OTHER THAN ELECTROLYSIS

Introduced: September 1968

Description

C23G covers chemical cleaning and degreasing processes for metallic materials using non-electrochemical methods, including acid pickling, alkaline cleaning, solvent degreasing, and passivation treatments. These processes remove contaminants such as oxides, oils, greases, and other surface impurities prior to further metallurgical operations or coating application. The classification excludes electrochemical cleaning methods (covered under C23F) and mechanical cleaning techniques, focusing specifically on chemical attack and dissolution mechanisms.
