A significant advance in Passivation Testing. Passive stainless steel is non-reactive with its environment. It is non-corroding. The passivation bath, usually nitric or citric acid, cleans off surface free iron which causes rust spots and also conditions the surface for the spontaneous formation of protective surface oxides. In effect, an equi-potential surface is formed by passivation. The surface free iron can come from various metal working and polishing steps. To eliminate these rust spots on stainless steel, testing for complete passivation is essential, and in most cases, an integral part of industrial and government contracts.

Up to now passivation verification consisted of the old-fashioned clumsy copper sulfate or ferroxyl tests or the lengthy and complicated humidity and salt spray testing. But in selecting the Passivation Kit 3036 Flash you've chosen a rapid response method for your verification demands. Federal Spec QQ-P-35C approved electronic meters to evaluate corrosion potential measurement as a method of checking passivation, so the Passivation Kit 3036 Flash can be used with complete confidence.

The Flash measures the corrosion tendency of the surface of stainless steels. It detects surface free iron through a galvanic process. A typical test, taking only 1-2 seconds, is simple: Electrical contact is made between a test piece through a moist wick.

This measurement can be repeated over the surface of the test part and at sensitive spots, such as seams and welds. Values for passive and non-passive readings are included in the instructions and a passivation standard 304 stainless steel coupon is provided for test comparison and instrument check-out. Test samples reading non-passive can then be retreated by running them through the passivation bath and then re-tested. The Flash can be used with all chromium containing stainless steels such as 300 and 400 series and the precipitation-hardened steels such as 17-4, 15-5, 17-7 and so on. Because no training is necessary the Flash can be used successfully by non-technical personnel.

A passive stainless steel standard is included in the kit.

Testing for passivation
by Peter Girten , Dec 01,2015

I’ve been speaking with other brewers, and everyone should know about the 3036. We are very pleased with the PassiFlash 3036 thus far.

We’ve been looking for a way to test passivation without using copper sulfate solutions, as we don’t want to have any of this inside of our tanks, and we don’t have a way to perform a salt spray test on the interior of our tanks. I did perform a few tests on some scrap stainless stock we had laying around – the results using the 3036 were consistent with the results from the copper sulfate tests.

We are now using the tester for every new tank we install to verify our passivation techniques, and we are also using the tester to determine how long the acid cycle of our tank CIP procedure really needs to be. We also discovered our acid cycles were inadequate for new tanks – we found that immediately after an acid cycle, a rinse, and drying, the surface would read unpassivated. After 4-8 hours, however, the surface would read passivated. Our nitric acid concentration was too low and/or our cycle time was too short. The procedure was sufficient to remove free iron from the surface, but we were not completely forming a chromium oxide layer – air was completing the process for us.

Passi-Flash 3036
by Julio C Nazario, Dec 01,2015

Everything is working out fine with our new stainless steel passivation tester; The Passi-Flash 3036. Our company is already highly ranked with our customers base; but when we added the new feature of printing out our logged data to our certification package our product credibility and customer confidence in our procedures was truly unquestionable . Much thanks to the Passi-Flash 3036. Keep on making great inventions like this one.

Thanks again.
