Carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel according to its
purpose. Carbon structural steel is further divided into engineering construction steel and machine-manufactured structural 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%); According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and
sulfur), high-quality carbon steel (lower phosphorus and sulfur), high-quality steel (lower phosphorus and sulfur) and special grade High-
quality steel.

Influencing factors

manganese About 0.25%~0.80%. Solid solution strengthening; removing FeO to reduce the brittleness of steel; and vulcanizing to synthesize
MnS, which can reduce the harmful effects of sulfur. Useful. silicon About 0.10%~0.40%, solid solution strengthening; beneficial in addition to
the adverse effects of FeO on steel quality. sulfur FeS and Fe form a low-melting eutectic (melting point is 985°C), which causes the steel to
become brittle and cracked during hot working at 1000~1250°C, which is "hot brittle". harmful.
