DC01 is a cold-rolled steel coil that is commonly used in the manufacturing of automotive parts, appliances, and other consumer goods. It is a low-carbon steel with a high level of formability, which makes it easy to work with and shape into various forms. The DC01 designation refers to the specific chemical composition and mechanical properties of the steel, which meet certain standards set by the European Union. Cold-rolled steel coils are produced by passing the steel through a series of rollers at room temperature, which results in a smoother and more uniform surface finish than hot-rolled steel.
