carbon steel sheet is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%.
it is also called carbon steel sheet. generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus.generally speaking, the higher the carbon content of carbon steel sheet, the harder and stronger it is.
