What level of Rust includes deep pitting in its description?

• A. Level 1
• B. Level 2
• C. Level 3
• D. Level 4

Answer: (C)

Deep pitting is a characteristic associated with Level 3 rust. At this stage, the corrosion has progressed beyond surface rust and has penetrated deeper into the material, creating significant pits and cavities. This level of rust indicates a more serious structural compromise, which typically requires more extensive repair or replacement measures. Levels of rusting are often defined by the severity of the corrosion and the degree of surface damage present. Level 1 typically refers to minor surface rust, while Level 2 indicates moderate corrosion without substantial material loss. Level 4 signifies an advanced state of rusting that may involve severe damage and extensive loss of material. Thus, understanding the classification of rust levels is crucial for determining appropriate maintenance and repair strategies in order to ensure safety and longevity of materials.
