“Restoring Purity, Preserving Integrity”
What Is Rouging
Rouging of stainless steel is the result of the formation of a layer of iron oxide, hydroxide or carbonate on the surface of the stainless steel. It is a thin layer with reddish-brown, yellow or black tones, and it can indicate a de-stabilization in the naturally occurring passive layer of stain-less steel. It typically occurs in high-temperature, high-purity environments and can compromise:
- Surface cleanliness
- Product purity
- Regulatory compliance
- Equipment lifespan
De-Rouging Process
