![]() This analysis shows that the magnetic nonlinearity of the low carbon steel is subjected to more changes as compared to magnetic Barkhausen noise with the change in the hardness. The samples of the medium carbon steel are tempered at different temperatures to analyze its hardness to be utilized for different applications. In this method, the non-linear magnetic mixing frequency measurements are made while taking different samples of medium carbon steel. There are different methods are used to measure the non-linear magnetic nature of the medium carbon steel but the mix frequency method is commonly used for the measurement of the non-linear behavior of the medium carbon steel. Medium carbon steel is magnetic but the magnetic nature is non-linear. The addition of manganese to the medium carbon steel results in its utilization as the crankshafts, gears, axles, shafts, and forgings. The increase of 0.5% carbon to the iron is accompanied by the addition of manganese to it. The medium carbon steel is harder than the low carbon steel but the ductility is reduced with the increase in carbon content. According to the manufacturing standard, the medium carbon steel contains carbon ranging from 0.30% to 0.60%. Medium carbon steel contains a high content of carbon in the iron as compared to low carbon steel. Related: Is Surgical Steel Magnetic? Medium Carbon Steel Thus, in these works there should be effective strategies should be used that do not allow to vary the magnetic properties of the low carbon steel. These properties include the magnetic flux density, magnetic permeability, and magnatraction coefficient. Low carbon steel possesses soft magnetic material properties and thus, due to the soft magnetic properties, the magnetic nature of low carbon steel is varied. However, the magnetic properties of the low carbon steel are severely affected due to the mechanical works i.e., forging of the low carbon steel. Thus, due to ferromagnetic nature of low carbon steel results in it as the magnetic material. Low carbon steel is magnetic because its magnetic domains are present in the form of ferromagnetic form. This is widely used in structural shapes i.e., channels, I-beams, and angle iron because of its physical and ferromagnetic properties. Low carbon steel is used to prepare the steel frame buildings, cookware, metal gates, fencing, and other machinery parts. It is stated as mild steel and it is extremely less expensive as compared to medium carbon steel or high carbon steel. According to the standard of the materials, the percentage of carbon in the low carbon steel is 0.30%. Low carbon steel comprises the low ratio of carbon to iron content. These materials possess strong permeability values and the magnetic domains of carbon steel are aligned by the magnets and these are easily attracted by the magnets. All grades of carbon steel including the duplex grades that are a mixture of ferrite and austenite are magnetic. However, if more carbon is added to the steel, then the magnetic properties i.e., permeability and coercivity are also increased and these are attracted by the magnets. In the case of low carbon content, the steel is stated as mild steel and mild steel is ferromagnetic. The magnetic properties of carbon steel depend on the amount of carbon in the steel. ![]() How the amount of carbon affects its magnetism?
