There are 4 they are Low Carbon steel, Medium Carbon Steel, High Carbon Steel and Eutectiod
Carbon steel, also called plain-carbon steel, is steel where the main alloying constituent is carbon
poor corrosion resistance
12L14 steel and SAE 1010 steel are not equivalent, though they are both low-carbon steels. 12L14 is a leaded steel known for its excellent machinability due to the addition of lead, while SAE 1010 is a plain carbon steel with a lower carbon content, offering good weldability and formability. The presence of lead in 12L14 makes it unsuitable for certain applications where lead contamination is a concern. Therefore, while they may share some characteristics, their properties and applications differ significantly.
The eutectoid point of plain carbon steel is approximately 0.76% carbon content. At this composition, the steel undergoes a phase transformation from austenite to a mixture of ferrite and cementite during cooling, resulting in the formation of pearlite microstructure.
Carbon steel due to the formation of pearlite layers of very weak and fragile, but the structural steel due to the strong molecular bonds are
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
Tool steel typically has a higher carbon content than mild steel. While mild steel generally contains about 0.05% to 0.25% carbon, tool steel can have carbon content ranging from 0.5% to over 1.5%. This increased carbon content in tool steel enhances its hardness and wear resistance, making it suitable for cutting tools and industrial applications, whereas mild steel is more malleable and ductile, making it ideal for structural applications.
The various uses of carbon steel depend on the amount of carbon added to the alloy; for instance, carbon steel with the lowest amount of carbon is called wrought iron and is used for things like fencing. Medium-carbon steel, also called mild steel, is the type of steel that is used for structural purposes in buildings and bridges. High-carbon steel is used for springs and steel wires, while ultra-high carbon steel is called cast iron and is often used to make pots.
50c8 is a variant of a plain carbon steel. You can refer any Enginnering Materials reference book to know more about it.
The most common steel is mild steel, also called plain-carbon steel. It's density is approximately 7.85g/cm3. (Wikipedia)
UNS K03005 refers to the chemistry restrictions placed on the carbon steel. The ASME/ASTM specification for this grade of carbon steel is A53 and is limited to 0.3% carbon, 1.2% manganese, 0.05% phosphorus, 0.06% sulfur. The balance is mostly iron, but tramp elements are not controlled.
