Cold rolled plate is a type of steel coil that has undergone cold rolling processing, and it is categorized under the samecold rolling as cold coils, cold plates, and cold-rolled strip steel. It uses hot-rolled coil as raw material, which undergoes pickling to remove oxide scale and then undergoes cold continuous rolling to form. Carbon steel, also known as plain carbon steel, has a carbon content of approximately 0.02%-2%. The main components of carbon steel cold rolled plate are iron and carbon, with the amount of carbon determining the hardness and strength of the steel. Different levels of carbon content enable carbon steel cold rolled plates to have various grades and properties to meet different industrial demands.
