I need to know the hardness for c - 45 steel.
The "R" in steel designation C45R typically indicates that the steel has been subjected to a surface hardening process, often through methods like hardening or hard chrome plating. This treatment enhances the surface hardness and wear resistance of the material while maintaining its core toughness. In the context of C45, which is a medium carbon steel, the "R" signifies a specific grade or type within the C45 category that is optimized for certain applications.
Yes.
Yes.
Mild steel, typically containing around 0.05% to 0.25% carbon, is known for its ductility, weldability, and ease of machining, making it suitable for general construction and fabrication. C45, on the other hand, is a medium carbon steel with a carbon content of approximately 0.45%, offering higher strength and hardness but lower ductility compared to mild steel. This makes C45 more suitable for applications requiring strength and wear resistance, such as gears and shafts, while mild steel is preferred for structural applications.
In the designation C45E, the "E" stands for "enhanced." This indicates that the steel has been treated or modified to improve its mechanical properties, such as strength and hardness, compared to the standard C45 grade. C45E is commonly used in engineering applications where higher performance is required.
C45 steel, which is a medium carbon steel commonly used for mechanical engineering applications, is equivalent to the Indian Standard IS 2026. Both standards specify similar chemical compositions and mechanical properties, making C45 suitable for applications like shafts, gears, and other structural components.
the equivalent for c45 is en-8 and en-19 is c55 Need the Chemical composition and mechanical properties of C45 and EN-8 also to C55 and EN-19

No, the chemical composition of C45 and EN8D steels are different. C45 is a European standard designation for a medium carbon steel, while EN8D is an Indian standard grade for a medium carbon steel. It is important to check the specific chemical composition of each grade to ensure suitability for the intended application.
DIN 1544-1.5-C45 refers to a specific standard for steel grades in Germany, where "DIN" stands for the German Institute for Standardization. The "C45" designation indicates a medium carbon steel with a carbon content of approximately 0.45%, known for its good machinability and strength. This standard specifies the technical requirements and quality for this type of steel, which is commonly used in engineering applications, including manufacturing parts and components.
EN9 and C45 are both medium carbon steels, but they have different chemical compositions and properties. EN9 typically has higher toughness and better wear resistance than C45, making it suitable for specific applications. However, whether you can substitute one for the other depends on the specific requirements of your project, including mechanical properties, heat treatment, and intended use. Always consult material specifications and standards to ensure compatibility.
