Do you have passsivation recommendations for us a little bit more detailed specifications than these in the AMS [link by ed.

If allowed to remain, the iron particles provide corrosion sites that will ultimately result in accelerated corrosion of the product.

Yet I never had any problems when we did use type II, and a few of our parts were H condition. Lee Kremer Stellar Solutions, Inc.

AMS 2700 Method 1 Type II Passivation for Medical Device

If the part passes the verification test, what differences in function can occur in the part’s use if differing acid baths are used? A renumbers those to 1 through 4 there is no such thing as A Type 6 or 7 while restores the missing four for a total of psasivation Types.

We design our own parts, and do our own passivation in house, and hence prefer the testing requirements of ASTM A Ken Vlach – Goleta, California.

Some customers ask for the parts passiavtion pass salt spray testing longer than A’s required 2 hours, etc.


AMS exempts C from testing. Hello, we’ve sent many parts to our different passivation vendors and pwssivation getting pasaivation that are “Flash attacked” or etched.
