Non-alloyed steels are called such as they do not have alloy elements within them other than traces possibly introduced by the use of used steel, such as that resulting from scrap. The difference between the different products present in this category of steel resides in the different carbon content, which influences the mechanical characteristics of the different steels.
Steel used initially in the automobile industry, with a limited carbon content. Limited surface hardness after induction tempering.

C43
Steel with more carbon than the previous one, very popular and used especially in Italy to obtain higher surface hardness.
This type is widely used in Germany instead of C45 and, thanks to the higher carbon, allows high surface hardness to be obtained.
This steel has the highest amount of carbon in this category, and is used in the automobile industry to obtain shafts and pins with high surface hardness to resist wear and sliding.
