Passivation is a non-electrolytic process using nitric acid that removes free iron from the surface and forms a protective oxide layer that renders the stainless steel to be more rust-resistant. Passivation also enhances the steel parts' corrosion resistance.

T&T Offer’s passivation of the following specs:

SAE AMS 2700 & QQ-P-35 TYPE 1
