Chromium-plated sheet rolls refer to steel plates that have a layer of chromium plated on their surface. This is done to prevent the [1] surface of the steel plate from being corroded and to extend its service life. A layer of metallic chromium is applied to the surface of the steel plate, and chromium plating is a commonly used and effective anti-corrosion method. The production cost is lower than that of tin-plated sheets, but it has strong adhesion and is 3 to 6 times stronger in adhering to organic coatings than tin-plated sheets. Its anti-sulfurization corrosion ability is also stronger than that of tin-plated sheets. Chromium-plated sheets can be produced in the form of continuous annealing (CA) or intermittent annealing (BA).
