A Pickling & Passivation Certificate for Electrolytic Polishing is a quality assurance document. It confirms that stainless steel (or another alloy) components have been chemically treated and surface-finished to meet corrosion resistance and cleanliness standards. The certificate ensures:
Identifies the customer, order, and part(s) treated.
Describes the surface treatment performed:
Pickling → removal of heat scale and oxides.
Passivation → creation of a protective oxide layer (usually via nitric/citric acid).
Electrolytic polishing → electrochemical smoothing and brightening of the surface.
Specifies the standards followed (e.g., ASTM A380, ASTM A967, EN standards).
Records process parameters (chemicals, temperatures, current, duration).
Confirms inspection results (visual, surface roughness, corrosion test if done).
Certifies compliance — signed and stamped by the manufacturer/processor.
