"We have provided a passivation system constructed of 304 SS to a customer. They are passivating to Method 1, Type 2 of AMS 2700. The dichromate portion of the liquor appears to be darkening the process tank\u2019s wetted surfaces only, as a non-dichromate liquor does not alter the tank\u2019s surfaces. Are we damaging the tank? Will the tank wear out prematurely? Will it adversely affect the passivation of the customer\u2019s parts?"^^<http://www.w3.org/2001/XMLSchema#string>
