Cadmium is used to coat fasteners for the simple reason that it works, and quite well. Cadmium is relatively easy to electroplate onto high strength steel, and for those steels whose strength is too high to tolerate the hydrogen embrittlement from electroplating, it can be vapor deposited ("vac cad" is the jargon).
Electroplated cadmium is a corrosion resistant cyanide coating, according to the Chem Processing Inc. Plating 304 stainless steel with cadmium gives the steel a number of advantages over uncoated stainless steel. These benefits include added corrosion resistance, malleability and non-reaction to aluminum. These attributes make it …
Generally, s/s dimpled washers are made of 3-series stainless, which has a higher nickel content. Without getting into the particulars, nickel is fairly compatible with other steels, and the cad plating is an attempt at further preserving the base metal of the screw. Obviously your biggest issue is with the cadmium plated screws rusting.

Painting over cadmium plating. Q. I am working on developing a re-lifeing process for 4130 Steel Tubes that have previously been Cadmium plated with a Di-Chromate seal and then painted. I would like to lightly plastic media blast the paint off and apply phosphate rather than chromate for paint adhesion purposes (ref AMSQQP416). …
Additionally, if exposed to certain chemicals like lye or ammonia, zinc can become brittle and crack over time. Finally, due to its weaker bond with steel relative to other types of plated metals, such as cadmium, zinc will wear away faster than some other coatings under certain conditions. Benefits of Cadmium Plating

Baking Northeast Metal Works operates several furnaces for the purpose of relieving hydrogen embrittlement in cadmium plated parts according to customer ...
Made of cadmium-plated steel, these internally threaded rod ends generally handle higher loads than stainless steel, aluminum, and nylon rod ends. Internally Threaded High-Speed Ball Bearing Rod Ends. Along with internal threads, these rod ends have a double row of precision ball bearings that allows high speeds and smooth operation.
What Does Cadmium Plating Mean? Cadmium plating is a technique used to coat metal surfaces with a layer of cadmium. This technique provides …
Published on: May 6, 2022. Metal plating is the process of applying a thin layer of metal coating on the metal surface, substrate, component, part, or product. The plating process achieves numerous benefits by combining the advantages of two different materials. For example, steel has positive mechanical characteristics like high strength, and ...
cadmium plating, especially for high-strength steel. Because hydrogen embrittlement is restrained when a titanium salt and hydrogen peroxide are added to a cyanide bath, this approach has been used for aircraft parts. Fluoborate solutions containing about 100 g/L cadmium, 60 g/L ammo-nium fluoborate, and 25 g/L boric acid have a cathode
Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments. Thin Heavy Flex-Top Locknuts for Heavy Vibration. About half the height and 10% wider than standard flex-top locknuts, these …

Passivated Stainless Steel: This material is preferred for hardware items like fasteners, primarily for its low cost and hardness. While it does not have the same ...
Cadmium by itself is a soft white metal that when incorporated onto powdered metal, copper, malleable iron, cast iron and steel becomes a coating that deteriorates before the material it protects. To maximize its corrosion protection, chromate conversion coatings are applied over the plated metal.
During production, the Arinc 600 connectors have been damaged (scratches) and need to be touched up. The shell of the connector is made in Aluminum per QQ-A-225/8 or QQ-A-591. The finish is cadmium plate per AMSQQP416 class 2 type II yellow with an underplating of electroless nickel per MIL-C-26074 [on DLA].
The sheer strengh of steel is 186,000 pounds per square inch.. The sheer strengh of stainless is 137, 000 pounds per square inch. Since steel's single-shear strength is typically 70% of tensile, it would take some super steel to get 186KSI. AN bolts have a tensile of around 120ksi and would have a shear strength of 84ksi.

Cadmium plating, also known as "cad plating," is an electroplating process that creates a sacial coating. The plating will corrode before the underlying substrate of steel, copper, iron, brass, or aluminum. Cad plating is widely used for plating in aerospace and defense applications that require additional corrosion resistance.
