Engineering 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. From the automotive trade to wider general engineering applications, EN8 is a popular steel in industry.

Key Features:

EN8 Engineering Steel is an unalloyed carbon steel with reasonable tensile strength. It can be flame or induction hardened and is a readily machinable material. When heat treated, EN8 offers moderate wear resistance.
