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.%)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



1045  Cold Rolled Steel Coil
AISI  1045 is a medium carbon steel designed to be able to function in areas  requiring greater strength and hardness. This steel possesses excellent size  accuracy, concentricity, and straightness which together minimize wear in  high speed applications. AISI 1045 can be formed into turned, ground and  polished coils that  can be machined unsymmetrically with limited distortion. They are often used in the production  of gears, shafts, axles, bolts, studs and  machine parts.
