Carbon steel: It is made of iron and carbon alloy. Carbon alloys containing high amounts of carbon, a steel that can be hardened and forged, are called cast iron. They are divided into three groups as low, medium and high carbon steels according to the amount of carbon they contain.
1-Low carbon steels: This group of steels, also known as soft steels, includes steels with a carbon ratio of up to 0.20%. Low carbon steels, which are generally flat products, are used extensively as bars and profiles in basic structures and in the construction industry.
2-Medium carbon steels: Steels with a carbon content between 0.20% and 0.60% are included in this group. Medium carbon steels, which are identified according to the carbon ratio in their mechanical properties, can be hardened to the desired degree by heat treatment. Steels in this group, whose greatest feature is that they can be hardened to the desired degree, are used in the machine manufacturing industry.
3-High carbon steels: These are steels with a carbon content higher than 0.60%. This group of steels has high strength and low ductility under normal conditions. High carbon steels, which can gain high hardness by heat treatment, are generally used in the production of cutting and piercing tools and tools due to their cutting properties.
The Use Areas of Carbon Steel
High carbon steels, which are used as raw materials in the production of many objects used in daily life, are produced with great effort. This steel group, which is not easy to produce, is produced using very small values and its use areas vary according to the amount of carbon it contains.
Low carbon steels with a carbon content of up to 0.20% are used in the production of nuts, bolts, machine parts and building materials. Medium carbon steels with a carbon content between 0.20% and 0.60% are used to produce machine, bolt, nut, shaft, spiral and leaf springs, scissors and other cutting tools. Furthermore, materials produced from medium carbon steels include files, cutters, rails, picks-shovels and other ship parts.
Since high carbon steels with a carbon content of more than 0.60% can reach the desired hardness by heat treatment, materials such as bucket gear and mouldboard are produced from this group of steel. Carbon steels, whose use areas vary according to their hardness, are used in the production of set and cutting and piercing materials, extending the life of the materials produced and increasing their durability.
