Cadmium plated fasteners are not recommended for use in systems with temperatures exceeding what?

Cadmium plated fasteners are not recommended for use in systems with temperatures exceeding 400 degrees Fahrenheit due to the potential for degradation of the cadmium plating at higher temperatures. Cadmium has a relatively low melting point and begins to lose its protective properties when exposed to elevated temperatures.

When cadmium plating degrades, it can lead to the exposure of the underlying material, making it susceptible to corrosion and ultimately compromising the integrity of the fastener. Therefore, maintaining the temperature limits is essential to ensure the longevity and reliability of the fasteners in various applications.

In this context, while the other temperature thresholds may seem high, cadmium's performance and protective capabilities become unreliable beyond 400 degrees Fahrenheit, making it critical to adhere to this recommendation in relevant systems.
