The chrome is applied externally to the metal parts of the firearm, which may consist of steel, iron or cast iron, to strengthen their resistance to corrosion, wear and abrasion.

Chrome plating entails immersion in an electrolytic bath containing a chromium compound, which is deposited on the metal at a thickness that ranges from 5 to 50 μ in accordance with the customer’s request.
