EN8 Carbon Steel & All En Series Steel
EN8 is an unalloyed medium carbon steel which is used in applications where better properties than mild steel are required but where the costs do not justify the purchase of a steel alloy. EN8 can be heat treated to provide a good surface hardness and moderate wear resistance by flame or induction hardening processes.
EN stands for emergency number and is a European standard, though it was originally created by the British. EN numbers are used as a way to identify the specification, grade, and chemical components of metals; most commonly steels.
