Advantages of Cadmium Coated Stud Bolts?

09/20/2011 8:34 AM. Agreed, cadmium-plated fasteners were discontinued in the USA years ago in favor of zinc-plate. If you are using stainless steel flanges, I would recommend you do not use plated bolts at all. You should be using stainless steel fasteners with SS flanges to prevent carbon inclusion and loss of corrosion resistance in the flanges.

What's so special about Cadmium Plating?

Here's why NASA doesn't like Cadmium plating: 1. Cadmium is known to sublimate in a hard vacuum environment (especially at temperatures above 75° C). The sublimation products, which are conductive, can redeposit resulting in short circuits. The sublimation products may also interfere with sensitive optics. 2.
