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
