Product Short Description: Citric acid passivation offers attractive environmental advantages, soaps having success with mineral acid passivation and suffering no safety issues might want to stay the course. Also no disposal problems. Product Description: Citric acid passivation has become increasingly popular with manufacturers who want to avoid the use of mineral acids or solutions containing sodium dichromate, along with the disposal problems and greater safety concerns associated with their use. Citric acid is considered environmentally friendly in every respect. Although citric acid passivation offers attractive environmental advantages, soaps having success with mineral acid passivation and suffering no safety issues might want to stay the course. There may be no real need to change if those users have a clean soap, well-maintained and clean equipment, coolant tree of iron-containing soap dirt, and a process that yields good results. Passivation treatment in citric acid baths has been found useful for a large number of stainless steel families, including several individual stainless grades. The conventional nitric acid passivation methods are included for convenience. Note that the older nitric acid formulations are in volume percent, while newer citric acid concentrations are in weight percent. It is important to note. in implementing these procedures, that a careful balance of immersion time, bath temperature and concentration is critical to avoid the "flash attack" described earlier, The passivation treatment varies depending on chrome content and machinability characteristics of the grades in each family. Note the columns referring to Process 1 or Process 2. As shown in Figure 5, Process 1 involves fewer steps than Process 2

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

Product Short Description: Carpenter has developed the A-A-A (alkaline-acid-alkaline) process Product Description: To effectively passivate the free-machining stainless steels, Carpenter has developed the A-A-A (alkaline-acid-alkaline) process that neutralizes trapped acid. This method of passivation can be accomplished in less than 2 hours. Here is the step-by-step procedure: 1st Step : After degreasing, soak the parts for 30 minutes in a 5 percent solution of sodium hydroxide at 160ºF to 180ºF (71º C to 82º C). 2nd Step : Then rinse the part thoroughly in water. 3rd Step : Next, immerse the part for 30 minutes in a 20 percent-by-volume nitric acid solution containing 3 ounces per gallon (22 g/liter) of sodium dichromate at 120ºF to 140ºF (49º C to 60º C). After removing the part from this bath, flush it with water, then immerse it in the sodium hydroxide solution for another 30 minutes. Rinse the part again with water and dry it, completing the A-A-A method.
