Stainless steel passivation

How Does Passivation Protect Stainless Steel?

Passivation services remain a critical step in maximizing the essential corrosion resistance of parts and components machined from stainless steels. Passivation of stainless steel returns the substrate back to its original specifications by removing iron particles from the surface. Our team uses a chemical process to reduce iron content, which increases the chromium levels in stainless steel. As chromium reacts with air, it creates a corrosion-resistant chromium-oxide layer. This adds a new level of durability to an already durable material.

Certified ASTM A967 Passivation

Metal passivation requires a detail-oriented approach. Our team meets the high standards of the American Society for Testing and Materials (ASTM), which incorporates cleaning, passivation and testing for stainless steel parts.

In order to ensure corrosion resistance, the ASTM A967 standard requires that there is no free iron on the metal’s surface. This important factor often determines the effectiveness of a stainless steel component.

Why Should You Passivate Stainless Steel?

Many applications that make use of stainless steel require maximum corrosion resistance. The most effective way to protect a stainless steel surface from degradation is by altering it into a passivated state. The passivation process leaves a chromium oxide film on the stainless steel surface, and this protective oxide layer does not react with air or water to the same degree as unpassivated stainless steel.
