    Uniform Corrosion

    Metal thins evenly or gets a uniform layer of corrosion.

    Galvanic Corrosion

    Two different metals touch in a salty environment, causing one to corrode faster.

    Crevice Corrosion

    Forms in small gaps, often much faster than uniform corrosion.

    Pitting Corrosion

    Creates deep, narrow holes, especially in stainless steel.

    Intergranular Corrosion

    Moves along grain boundaries, which can cause sudden failure.

    Stress Corrosion Cracking

    Cracks form under tension in a corrosive setting, leading to unpredictable failures.

    Impact on Power Distribution Reliability

    Corrosion does more than just weaken metal. It can cause your Smart Power Distribution Unit to lose reliability over time. Localized pitting and cumulative damage compromise the structure and function of your equipment. You need to manage these risks to keep your systems running.
