Spot Passivation?

adv.   stellar solutions banner

(2001)

I have heard the term spot passivation used. Is this a true passivation or more of a cleaning of the surface area? If this is a true passivation how does one validate it?

Thanks for your response.

Gregory:

Spot passivation is typically used in the field for welds, etc. after assembly of units or for units that cannot be put into a tank. There are gelled products available that make this fairly easy to do, and very effective. It is true passivation, and you can test for it in different ways, depending on the grade of stainless steel. See ASTM A967 [link by ed. to spec at TechStreet] 7.

Please contact us if you need products or advice about how to do this.
