AMS 2700 Passivation

Aerospace-specification passivation services in full compliance with AMS 2700 for corrosion-resistant steels used in flight-critical and high-reliability components.

Specification Overview

AMS 2700 is an aerospace specification that defines the chemical treatments used to passivate corrosion-resistant steels. It ensures removal of free iron, enhances surface oxide formation, and verifies corrosion resistance using standardized test methods.

Methods include Nitric 1–4 and Citric 1–3
Applicable to 300, 400 series, PH, and martensitic stainless steels
Post-passivation tests include salt spray and copper sulfate
Used in aerospace, medical, and precision mechanical assemblies
