ASTM-A967

The passivation process is primarily used to improve the surface condition of stainless steel by dissolving the non-alloyed elements that have been exposed on the surface of the metal while forming, machining or during other manufacturing operations. During the passivation process, a film is created that causes the surface to lose its chemical reactivity. Stainless steel is already known as being corrosion resistant; however, the passivation process further strengthens its’ natural ability by improving the exterior surface of the overall part resulting in a very low corrosion rate of the metal.

We currently offer Nitric Acid passivation for stainless steel parts up to 4 feet in length.
