Passivation

Passivation is a chemical treatment process that removes free iron and other surface contaminants from stainless steel, allowing the natural chromium oxide passive layer to reform and strengthen. The result is a cleaner, more corrosion-resistant surface that exceeds industry standards.

Pure Source performs passivation for a wide range of components, from small machined parts to large process vessels and piping systems. We offer both shop-based and on-site field service, giving you flexibility based on the size and sensitivity of your equipment.

Our passivation services comply with ASTM A967 and ASTM A380, the primary standards governing passivation methods, testing, and acceptance criteria. We perform supervised test verification to support your quality requirements.
