  • Main Corrosion Forms Of Stainless Steel Materials
    Dec 25, 2018

    The main corrosion forms of stainless steel are as follows:

    1. Uniform corrosion: Uniform corrosion refers to the corrosion of all metal surfaces in contact with corrosive media.

    2. Point corrosion: Point corrosion refers to the high degree of local corrosion occurring on the surface of most metal materials without corrosion or slight corrosion. The size of common corrosion points is less than 1.0 mm, the depth is often greater than the surface aperture, the light ones have shallow pits, and even serious perforations.

    3. Crevice corrosion: Crevice corrosion refers to the occurrence of spot-like pits in the crevices of metal components, which is a kind of local corrosion.

    4. Intergranular corrosion: Intergranular corrosion is a selective corrosion failure. The locality of corrosion is micro-scale, but not necessarily local in macro-scale.

    5. Total corrosion: Total corrosion occurs on the whole alloy surface in a relatively uniform manner.
