If the surface of a cladded product is scratched to a depth below the thickness of the cladding, what may happen?

Explanation:
Cladding is there to act as a protective barrier against corrosion. When the surface is scratched to a depth that reaches the substrate, you break that barrier and expose fresh metal to the surrounding environment. Moisture, oxygen, and any aggressive chemicals can then initiate corrosion right at the exposed area. The breach is the key risk factor—the underlying metal becomes susceptible to corrosion, whereas intact cladding elsewhere continues to shield it. While delamination or wear could occur in different scenarios, the immediate concern after a scratch like this is that corrosion may start on the exposed substrate.
