C45 Steel

Product Description:

C45 is a medium carbon steel, also known as 1.0503 steel according to the EN standard, that is commonly used for manufacturing parts requiring good tensile strength, wear resistance, and hardness. It is a non-alloy steel, meaning it does not contain significant amounts of other alloying elements like chromium, nickel, or molybdenum, although it may contain small amounts of manganese, sulfur, and phosphorus.
