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.%)MicrostructurePropertiesExamples
Low-carbon steel< 0.25Ferrite, pearliteLow hardness and cost. High ductility, toughness, machinability and weldability
Medium-carbon steel0.25 – 0.60MartensiteLow hardenability, medium strength, ductility and toughness
High-carbon steel0.60 – 1.25PearliteHigh hardness, strength, low ductility

PRODUCT DETAILS


DC01/DC02/DC03/DC04  Cold Rolled Steel Plate
DC  steel plates have high tensile strength and elongation, giving them good  processing properties during the manufacturing process and is easy to bend,  stamp, form and weld. This makes DC steel plates widely used in the  manufacturing of automotive parts, home appliances, construction and other  parts that require high strength and precision. DC steel plates’ s low carbon content gives  them excellent weldability and machinability. They 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, the carbon emission is low and meets  the requirements of environmental protection and sustainable development.
