is a type of steel containing carbon elements, and its carbon content is usually between {{0}}.12% and 2.0%. The carbon content determines the hardness and strength of carbon steel. The strength of ordinary carbon steel is around 400MPa to 500MPa, while high-strength carbon steel can reach more than 1000MPa.
1. Classification by use
can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel.
Free-cutting structural steel is made by adding some elements that make the steel brittle, so that the chips are easily broken into chips when the steel is cut, which is conducive to increasing the cutting speed and extending the tool life.
Carbon steel can be divided into open-hearth steel, converter steel, etc.
Carbon steel can be divided into rimming steel, killed steel, semi-killed steel and special killed steel.
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel. The carbon content of low carbon steel is {{0}}.02%~0.3%, the tempering time is short, it is soft, stamping resistant and ductile, and is mainly used for cold processing and welding structures; the carbon content of medium carbon steel is 0.25%~0.6%, and there are many products such as killed steel, semi-killed steel, rimming steel, etc., which can be used to manufacture various machine parts; the carbon content of high carbon steel is 0.6%~2%, which can be quenched and tempered, and is mainly used for general bearing tool carbon tool steel), rails, steel frame molds (used to shape steel) and steel doors, etc.
Carbon steel can be divided into ordinary carbon steel, high-quality carbon steel, high-grade high-quality steel and special high-quality steel.
