They are iron carbon alloys containing elements from steel production methods such as manganese, silicon, sulphur and phosphorus in small amounts. They are also known as manufacturing steels since their usage areas are the construction and manufacturing sector.

All properties of carbon steels are directly related to the structures they have, depending on the amount of carbon they contain. While hardness, yield and tensile strength of steels increase with increasing carbon content, ductility (% elongation and % cross-sectional shrinkage) and impact strength properties decrease. The increase in carbon content (depending on these properties) plays a decreasing role in the plastic deformability of steels. On the other hand, as a very important and effective element in martensitic transformation, it makes it possible to harden steels by the mechanism we call quenching. The increase in the amount of carbon has an inverse effect on the quenching ability and welding ability of the steel.

Application Areas of Carbon Steels

The amount of carbon in the content of carbon steels also changes their usage areas. Since the amount of carbon changes the properties and structure of the steel, the usage areas of all carbon steels are different from each other. For example, low carbon steels are mostly used in the manufacture of machine parts such as nuts and bolts, as well as in construction and building areas. Medium carbon steels are used in the production of things such as nuts, machines, bolts, spindles, ship shafts, axles, gear wheels, milled shafts, transmission shafts, lever arms, picks, rails, shovels and load hooks.

Finally, high carbon steels are used to make tools such as nuts, spirals, shafts, bolts, bolts, shafts, leaf springs, bucket gears, shears, grader blades, cutting tools, high machinery parts, wood saws, files and cutters. High carbon steels can be further hardened by using heat treatments.
