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



AISI/SAE  1018 Round Steel Bar Description
1018  cold rolled steel bar is made of a general-purpose, low-carbon steel with  good case hardening qualities. It is especially suited to cold  forming and bending operations. 1018 steel is suitable for parts  that require cold forming such as crimping, swaging, or bending. 1018 steel is mild steel with  medium-low carbon content. AISI 1018 carbon steel is a free machining grade  that is the most commonly available grade around the world. Although its  mechanical properties are not very unique, it still can be easily formed, machined,  welded and fabricated.
