Sodium Dichromate Manufacturer, supplier and exporter

After thorough cleaning, the stainless steel part is ready for immersion in a passivating acid bath. Any one of three approaches can be used--nitric acid passivation, nitric acid with sodium dichromate passivation and citric acid passivation. Which approach to use depends on the grade of stainless steel and prescribed acceptance criteria.

More resistant chromium-nickel grades can be passivated in a 20 percent-by-volume nitric acid bath . As indicated in the same table, less resistant stainless grades can be passivated by adding sodium dichromate to the nitric acid bath to make the solution more oxidizing and capable of forming a passive film on the surface.

Another option, used in place of nitric acid plus sodium dichromate, is to increase the concentration of nitric acid to 50 percent-by-volume , The sodium dichromate addition and lit : higher nitric acid concentration both reduce the chance of undesirable flash attack.

Sodium Dichromate is a chemical used as passivation. ... "The appearance of galvanized steel after quenching with sodium dichromate will be yellowish in color.
5% sodium dichromate is 50,000 ppm sodium dichromate. The usual sodium dichromate concentration of my clients is between 100 ppm and 500 ppm sodium dichromate. Also the pH of the dichromate tank MUST be held between about pH 4 and pH 4.5 or it will not properly function (adjust pH downward with very small amounts of HCl). The appearance of the SOLUTION is a very light yellow NOT ORANGE.
