Advanced Plating Technologies (APT) offers passivation to all methods listed within ASTM A967, AMS 2700 and QQ-P-35. In addition, APT can meet the requirements of any company-specific nitric or citric acid stainless steel passivation methods. APT also provides passivation of stainless steel to the Carpenter A-A-A process to passivate difficult stainless steel alloys including high-sulfur free machining 303 or 416 alloys as well as high chromium alloys such as 440 stainless (reference: A-A-A Passivation Methods article in our Metal Finishing White Papers section). Inhibited passivation solutions are available to maintain bright surfaces of stainless components such as machined faces and centerless ground 303 or 416 stainless steel shafts.

QQ-P-35 does not cover citric acid passivation services. Four active nitric acid passivation services are covered as follows (four inactive methods have been withdrawn):

Stainless steel or corrosion-resistant steel (CRES) is defined as a steel alloy with a minimum of 11% chromium content by weight. Many alloys of stainless steel include substantial nickel to further enhance the corrosion resistance. In general, stainless steel is broken down into three main groups based upon the alloying elements and Passivation of stainless steel click lockscompositions as follows: 1) Austenitic Grades (all 200 & 300-series), 2) Ferritic Grades (part of the 400-series, low carbon alloys) and 3) Martensitic Grades (part of the 400-series, higher carbon alloys).

When stainless steel products are manufactured, free iron is transferred to the surface of the material from the steel cutting, stamping and forming tools used in the manufacturing process. Free iron can also be imparted on the surface by polishing or blasting operations that utilize the same polish or blast media between both mild steel and corrosion resistant steel grades. Free iron readily oxidizes, forming visible rust on the surface of the product. Passivation is a chemical treatment with a specific acid formulation that removes free-iron or other surface contamination from the stainless steel while simultaneously promoting the formation of a passive chromium/nickel oxide layer to act as a barrier to further corrosion.

Various corrosion resistance tests are defined within AMS 2700. However, it is noted that certain alloys such as high carbon alloys with 0.85% carbon or more (such as 440C) are exempt from various testing requirements due to false positives that can result. Parts shall meet one or more of the following tests:

It is important to note that stainless steel is corrosion resistant but not corrosion proof. The degree of corrosion resistance of a stainless steel alloy is a function of the alloying composition, heat treatment, internal stresses and passivation treatment. An example of this phenomenon is 303 free-machining stainless steel which has notably less corrosion resistance than 304 stainless steel due to the higher concentration of sulfur and phosphorous that imparts the desired machinability of the 303 grade. As a general rule, the higher the nickel and chromium content in the alloy, the more corrosion resistance it will have.

Si deseas defenderte de una acusación falsa o uno de tus familiares ha sido víctima de un abuso, debes buscar asesoría legal de inmediato.

The reason for the stain-less nature of stainless steel is due to the formation of a thin, adherent and passive (nonreactive) film of nickel & chromium oxides that forms a barrier to prevent further surface corrosion of the product. This is in stark contrast to iron oxide (red rust) that forms on plain carbon steel products. Iron oxide is a loose, scaly oxide that easily falls away to allow the formation of additional iron oxide, thereby perpetuating the corrosion reaction.

3.1.3.1 Bath Composition: Parts shall be immersed in an aqueous solution of 4 to 10 percent citric acid, with additional wetting agents and inhibitors as applicable. 3.1.3.2.1 Temperature: Bath temperature shall be 70 to 160F (21 to 71C) with an immersion time of not less than 4 minutes for baths operating over 140F (60C), not less than 10 minutes for baths operating in the 120 to 140F (49 to 60C) range, not less than 20 minutes for baths operating in the range of 100 to 119F (38 to 48C) or not less than 30 minutes for baths operating below 100F (38C).

Unfortunately, very few part prints indicate the specific passivation method to be employed. This opens the door for finishing job shops to use any convenient method they have available resulting in a part that has been passivated but is not truly passive (reference: How to Prevent Corrosion on Passivated Stainless Steel Products in our Plating Topics section). APT’s experience in passivation ensures that the correct passivation method will be selected to match the specific stainless steel grade. Advanced Plating Technologies provides full in-house testing services to certify the performance of our stainless steel passivation including high humidity, salt spray per ASTM B117, potassium ferricyanide.
