Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally, it also contains a small amount of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.
Because no other alloying elements are added, it is easier to oxidize and rust. The higher the carbon steel content, the greater the hardness, the higher the strength, the lower the plasticity, and the lower the price.
