Carbon steel is categorized into low carbon steel, medium carbon steel, and high carbon steel based on its carbon content. Low, medium, and high carbon steel have maximum carbon contents of 0.25%, 0.25-0.5%, and 0.5-1.25%. Therefore, S45C S45Cand S50C are medium carbon steel.
Properties: S45C and S50C are known as carbon steel for mechanical structures with chemical compositions of carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, and copper. "C" stands for carbon,"45" and "50" stand for 0.45% and 0.50% carbon contents. The carbon content is what determines the hardness and strength of the steel. The higher the carbon content, the higher the hardness of the steel, but also the more brittle it is. S50C is also a material that is mostly used for mechanical parts, etc., just like S45C. However, S50C is also classified as a material with a high carbon content among medium carbon steel materials. S50C has higher hardness, tensile strength, and wear resistance than S45C, and is therefore used for parts that require higher strength.
Application: Due to their high hardness, toughness, and wear resistance, they can be used in many fields, such as mechanical engineering, automotive, shipbuilding, metallurgy and mining, and the petrochemical industry.S45C is mainly used for mechanical parts, especially inside machinery. It is an extremely common material for mechanical components. S50C is preferred over S45C when higher strength and toughness are required, such as shaft parts, gears, pins, nuts, bolts, and molds. When selecting materials, in addition to strength and hardness, the shapes of materials available on the market should also be considered. Shapes and specifications that are difficult to obtain can be replaced with materials with similar properties. Conclusion: S45C and S50C are popular materials for machinery and structural. But the S45C is more popular in the market. Following years of use, we are becoming increasingly familiar with the properties of medium carbon steel, and the issues associated with its application are also being resolved.
