Surface Hardening Steels Non-Alloyed

Carbon-Only Steels for Induction Hardening

Surface hardening steels non-alloyed 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.
