Plain Carbon Steels: Classification and Limitations | Metallurgy
These steels have carbon content in between 0.15% to 0.25%, i.e., higher carbon content than conventional low carbon steels and thus, have higher strengths but lower ductility, and thus are hot worked steels. As these steels too are not hardened, these are air cooled (normalised) after hot rolling, or forging, etc.

Cast irons and their Classification
Depending on the silicon content and the cooling rate, the pearlite in iron can vary in carbon content. This is a ternary system, and the carbon content of pearlite can be as low as 0.50 % with 2.5 % Si. The measured hardness of graphitic cast irons is influenced by the graphite, especially in gray cast iron.

Classification of Cast Iron
Cast irons are multicomponent ferrous alloys. They contain major (iron, carbon, silicon), minor (0.01%), and often alloying (>0.01%) elements. Cast iron has higher carbon and silicon contents than steel. Because of the higher carbon content, the structure of cast iron, as opposed to that of steel, exhibits a rich carbon phase.

That is why, single most-widely used steels are low carbon steels having less than 0.10 % carbon (welding of blow-holes becomes increasingly difficult with the increase in carbon content of the steels, particularly when the carbon content is more than 0.3 %). Capped steels find better use, when the carbon is more than 0.15%.

Fly ash properties, characterization, and applications: A review
The carbon content differences between FA classes are performed by calculating the loss on ignition (LOI). LOI is higher when more unburnt carbon is present. Consequently, Class F (LOI) is higher than Class C. Fig. 4 summarizes the main differences between class C and F as claimed by ASTM ( Hower et al., 2001 ).
