AMS 2700 vs. AMS QQ-P35

Do the parameters in A cover any worst case scenario? All The specifications are the same, then why are the Names different? If you are working to a DoD requirement you are allowed to switch to either of the referenced specs. Which Type with Which Grade? As you see, we added your question to a thread which already answers it.

Red Flag This Post Please let us know here why this post is inappropriate. If so, how could I support that statement? Lee Gearhart metallurgist. If you do not specify, they can use whatever they want, even ways that are not in any of the specifications! Thank you for your hard work which the finishing world continues to benefit from.

Download Now With over years of production history, the automotive industry has been at the forefront of manufacturing technology since its inception. The Eng-Tips staff will check this out and take appropriate action. Free iron can also be imparted on the surface by polishing or blasting operations that utilize the same polish or blast media between both mild steel and corrosion resistant steel grades.

What is standard to you may not be standard to them. Inhibited passivation solutions are available to maintain bright surfaces of stainless components such as machined faces and centerless ground or stainless steel shafts.

AMS Passivation Standards

Don't ask how you revise cancelled specifications. Other combinations of temperature, time, and acid with or without accelerants, inhibitors or proprietary solutions capable of producing parts that pass the specified test requirements. We have both specs in house.

AMSF Passivation of Corrosion Resistant Steels - SAE International

You can guess the increase in the amount of testing involved. The best thing do to is ask the customer what they expect.

By joining you are opting in to receive e-mail. Resources Aerospace manufacturing has always been on the cutting edge, from materials to production techniques. And there are other differences. Ray, Thank you for answering. Have the plater do so, and then certify to multiple standards.

This is in stark contrast to iron oxide red rust that forms on plain carbon steel products. However, these two aspects of aerospace machining can conflict, as manufacturers strive to maintain machining efficiency with new materials by using new methods and cutting tools.

But if it's a medical instrument or implant, then you're also going to have to show the appropriate tribute to an F standard. This the link is a revised cancellation notice. Students Click Here Join Us!

There are other in-house specifications for some companies. This auditor you are dealing with, what organization is he with? In reading through the specification I believe the drawing is incorrect.

AMS 2700 Passivation Standard

Promoting, selling, recruiting, punjabi bhajans coursework and thesis posting is forbidden. It's not possible to diagnose a finishing problem or the hazards of an operation via these pages. Join your peers on the Internet's largest technical engineering professional community.

Is there any clear direction or is it optional? Why did these types comeback and what metals do we associate with these metal types? Is this a correct assessment? Lee Kremer Stellar Solutions, Inc. Are the types listed in the two different specs identical?

Free iron readily oxidizes, forming visible rust on the surface of the product. The notes and tables are all there. Indeed also my conclusion is that it is an omission. But again, please describe your situation. Which is the right passivation spec?

AMS 2700 Which Type with Which Grade

Is one better than another for medical devices? Aerospace manufacturing has always been on the cutting edge, from materials to production techniques. Iron oxide is a loose, scaly oxide that easily falls away to allow the formation of additional iron oxide, thereby perpetuating the corrosion reaction.

ASTM A967 vs. AMS 2700 Which is the right passivation specAMS 2700 vs. AMS QQ-P35

It's easy to join and it's free. What requirement or standard is he auditing you against, since clearly it is not A? Isn't there a table to tell you which are applicable?

When stainless steel products are manufactured, free iron is transferred to the surface of the material from the steel cutting, stamping and forming tools used in the manufacturing process. Are you an Engineering professional? Unfortunately, very few part prints indicate the specific method of passivation of stainless steel to be employed. The degree of corrosion resistance of a stainless steel alloy is a function of the alloying composition, heat treatment, internal stresses and passivation treatment.
