EN8 is an unalloyed medium carbon steel that 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.

POPULAR STEEL GRADE

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 the industry.

SUITABILITY

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.
