Ferroxyl testing is a highly sensitive quality assurance procedure performed when zero tolerance for free iron, iron oxide, or surface contamination exists on passivated stainless-steel components.
Fortune Seven provides both field and laboratory testing in strict accordance with ASTM A380 and ASTM A967 standards. Utilizing specialized potassium ferricyanide indicator solutions, our testing identifies invisible iron particles, iron-tool marks, residual pickling salts, embedded iron, and weld deposits before they trigger premature corrosion or product failure.
ASTM Standard Compliance: Executed strictly in alignment with ASTM A380 (Cleaning, Descaling, and Passivation) and ASTM A967 (Chemical Passivation Treatments).
Ultra-Sensitive Detection: Instantly reveals minute free iron particles, iron-tool transfer, weld zone deposits, and residual pickling salts.
Passivation Quality Assurance: Serves as a definitive confirmation test to verify the continuity and integrity of the protective chromium-oxide layer.
Targeted Industrial Application: Ideal for critical pharmaceutical, chemical, oil & gas, and offshore equipment (Note: Formulations containing Potassium Ferricyanide are strictly reserved for non-food contact surfaces).
