Is c-45 the same as aisi 1045?

Answer 1

C-45 and AISI 1045 refer to the same grade of carbon steel, with C-45 being the designation used in Europe and other regions, while AISI 1045 is the designation used in the United States. Both have similar chemical compositions, typically containing around 0.45% carbon, which gives them good strength and hardness properties. However, specific mechanical properties and manufacturing standards may vary slightly between regions. Always consult relevant standards for precise applications.
