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 [1]. 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

ПОДРОБНАЯ ИНФОРМАЦИЯ О ПРОДУКТЕ

1023 Cold
Rolled Steel Plate

1023
cold rolled steel plate is made of low-carbon alloy steel designed for use in
applications that require excellent machinability and formability. This type
of steel comes with outstanding weldability and machinability, making it an
ideal choice for various applications. Its composition mainly includes iron,
carbon, and manganese. 1023 steel plate does not have strong heat resistance
compared to other steels due to its low carbon content; therefore it should
not be used for applications requiring high temperature operation unless
proper heat treatments are applied beforehand such as tempering or annealing.
