Carbon Steel: Properties, Production, Examples and Applications

Carbon steel is an iron-carbon alloy, which contains up to 2.1 wt.% carbon. For carbon steels, there is no minimum specified content of other alloying elements, however, they often contain manganese. The maximum manganese, silicon and copper content should be less than 1.65 wt.%, 0.6 wt.% and 0.6 wt.%, respectively.

Types of carbon steel and their properties

Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel . Their carbon content, microstructure and properties compare as follows:

Carbon content (wt.%)	Microstructure	Properties	Examples
Low-carbon steel	< 0.25	Ferrite, pearlite	Low hardness and cost. High ductility, toughness, machinability and weldability	AISI 304, ASTM A815, AISI 316L
Medium-carbon steel	0.25 – 0.60	Martensite	Low hardenability, medium strength, ductility and toughness	AISI 409, ASTM A29, SCM435
High-carbon steel	0.60 – 1.25	Pearlite	High hardness, strength, low ductility	AISI 440C, EN 10088-3

PRODUKTDETAILS

DC01/DC02/DC03/DC04
Cold Rolled Steel Coil

DC
steel coils have high tensile strength and elongation, giving them good
processing properties during the manufacturing process. This makes DC steel
coil widely used in the manufacturing of automotive parts, home appliances,
construction and other parts that require high strength and precision. DC
steel coil has excellent weldability and machinability with its low carbon
content. So it can be processed through various welding and cutting
processes, such as arc welding, gas shielded welding, laser cutting, etc., to
meet the needs of material processing performance in different fields.
Lastly, it meets the requirements of environmental protection and sustainable
development by releasing low carbon emission.
