Carbon Steel

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. The higher the carbon content in carbon steel, the greater the hardness and the higher the strength, but the lower the plasticity.

According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and high-grade fine steel (lower phosphorus and sulfur content) and  high quality superfine steel.

According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%)

Additional Information

Carbon steel can get higher hardness and better wear resistance after heat treatment.

The hardness of carbon steel in the annealed state is very moderate, and it also has good machinability.

The raw materials of carbon steel are very common, easy to obtain, and the production cost is relatively low.

Application

It is mainly used in the production of instruments, watch parts, automobiles, machine tools and other various machines with small force and strict requirements on size and finish. standard parts, such as gears, shafts, bolts, valves, bushings, pins, pipe joints, spring seat cushions and machine tool screws, plastic molding dies, surgical and dental procedures, etc.
