Is passivation a Nadcap process?
NADCAP Certified Passivation – Nitric and Citric Passivation is an immersion process designed to enhance the corrosion protection of stainless steel.
What chemicals are used for passivation?
There are three chemicals broadly used for passivating stainless steel; phosphoric acid, nitric acid, and citric acid. Each has its relative strengths compared to the others making them more suitable to certain applications over others.
Is standard for passivation?
The ASTM A967 passivation standard applies to the cleaning, passivation and testing of stainless steel parts. Chemical passivation removes free iron and other surface contaminants from stainless steel parts, improving corrosion resistance.
How do you become Nadcap certified?
The Nadcap accreditation process requires you to perform an internal audit – a form of self-assessment that is used to measure your strengths and weaknesses against the Nadcap audit requirements [1] – and submit the results at least 30 days prior to the official audit.
Is ASTM A967 the same as AMS 2700?
There are other differences- ASTM A967 allows the use of any mix of nitric and water, so long as you show it works (Nitric 5 solution). The ASTM doesn’t default to the nitric acid formulations, as AMS 2700 does. AMS 2700 has an iron concentration maximum, absent from ASTM A 967. AMS 2700 exempts 440C from testing.
What is Nadcap approved?
Nadcap accreditation is an industry driven program where highly qualified individuals, having experience in the aerospace industry conduct the actual process audits, using criteria specific to an actual process. This accreditation is intended for organizations doing business in the aerospace industry.
What is a passivation certificate?
Passivation of stainless steel is a process that removes free iron from the surface of a stainless component and at the same time promotes the formation of a thin, dense oxide protective barrier.
What metals can be passivated?
Chromate conversion is a common way of passivating not only aluminium, but also zinc, cadmium, copper, silver, magnesium, and tin alloys. Anodizing is an electrolytic process that forms a thicker oxide layer. The anodic coating consists of hydrated aluminium oxide and is considered resistant to corrosion and abrasion.

How do I get Nadcap certified?
What is Nadcap approval?
Nadcap (National Aerospace and Defense Contractors Accreditation Program) is an industry-managed approach to conformity assessment of ‘special processes’. ATS is proud to be listed as one of the Nadcap Approved Suppliers within several of our service industries.
What is Nadcap plating?
NADCAP Approved Plating Administered by the Performance Review Institute (PRI), NADCAP is a global cooperative accreditation program that establishes strict standards for chemical processing including metal plating. The plating services offered by companies should undergo an audit and accreditation process to become NADCAP certified.
Is AATS Nadcap approved?
