what is carbon steel

Carbon steel is a type of steel that contains carbon as the primary alloying element, with a carbon content ranging from about 0.05% up to 2.5% by weight. The American Iron and Steel Institute defines carbon steel as steel with no minimum content specified for any alloying element, other than carbon. Carbon steel may also contain other elements, such as manganese, phosphorus, sulfur, and silicon, which can affect its properties. Carbon steel is a popular metal choice for knife-making due to its high amount of carbon, giving the blade more edge retention. Carbon steel can be easily machined and welded, making it versatile for various applications. It can also be heat treated to improve its strength, hardness, and durability. However, carbon steel is susceptible to rust and corrosion, especially in environments with high moisture levels and/or salt. Carbon steel is also an environmentally friendly material, as it is easily recyclable and can be reused in various applications. It is also energy-efficient to produce, as it requires less energy than other metals.
