En-8 (1040) It is an unalloyed medium carbon steel with reasonable tensile strength. It is usually supplied in a cold drawn or rolled state. Tensile properties may vary, but are usually between 500 - 800 N/mm. It is widely used in applications that require better performance than mild steel but cannot justify the cost of alloy steel. EN8 can be flame or induction hardened to produce good surface hardness and moderate wear resistance.
