Both contain a carryover of QQ-PC with the addition of the more recently developed citric acid based process. Is this a correct assessment? October 23, A.

Ken Vlach – Goleta, California. AMS exempts C from testing. To me this means volume percent of pure nitric acid, resulting in significantly stronger passivation solutions than AMS There are other in-house specifications for some companies.

All information presented is for general reference and does not wms a professional opinion nor the policy of an author’s employer.
