Stainless Steel Restoration & Passivation
Protecting the Performance of High-Purity Stainless Steel Systems
Professional passivation, free iron removal, corrosion restoration, and surface conditioning for biotechnology, pharmaceutical, food processing, marine, and industrial stainless steel equipment.
Restore corrosion resistance. Extend service life. Protect product integrity.
Why Surface Restoration Matters
Even properly fabricated stainless steel can lose its natural corrosion resistance after welding, machining, grinding, handling, or prolonged service. Surface contamination, embedded free iron, heat tint, and oxidation can compromise both appearance and performance.
ANF Fabrications Inc. restores stainless steel surfaces through professional passivation and restoration techniques designed to improve corrosion resistance, extend equipment life, and support compliance in regulated manufacturing environments.
Whether restoring an aging process system or treating newly fabricated equipment, we focus on protecting the integrity of every stainless-steel surface.
