Metal Treatment-68

Variations

Sodium Dichromate BICHROMATE

Short Description

The sodium dichromate addition and lit : higher nitric acid concentration both reduce the chance of undesirable flash attack.

Other Equivalent Brand Products

Also known as

Passivation additive for NITRIC ACID, SODIUM BICHROMATE, Na2 Cr2O72H2O

Product Description

Sodium Dichromate Manufacturer, supplier and exporter

Application

Dichromates are power oxidizing agents which find applications in:

Chromium source in preparing chromium compounds
Leather tanning and screen printing
Electroplating
Pyrotechnics and explosives
Pigment preparation
Wood Preservative
Metal Treating and corrosion inhibitor
Oil drilling
Catalyst for the chromium metal production
Photographic engraving

In biological field, potassium dichromate is used as a fixative for used for conservation of tissue sections.

Dose

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.
