EN 8

EN8 carbon steel is a common medium carbon and medium tensile steel, with improved strength over mild steel, through-hardening medium carbon steel. EN8 carbon steel is also readily machinable in any condition.

EN8 steels are generally used in the as supplied untreated condition. But EN8 steels can be further surface-hardened by induction processes, producing components with enhanced wear resistance. Steel EN8 materials in its heat-treated forms possesses good homogenous metallurgical structures, giving consistent machining properties.

Good heat treatment results on sections larger than 65mm may still be achievable, but it should be noted that a fall-off in mechanical properties would be apparent approaching the centre of the bar. It is therefore recommended that larger sizes of EN8 steel materials are supplied in the untreated condition, and that any heat treatment is carried out after initial stock removal. This should achieve better mechanical properties towards the core.

    • Applications for EN 8 steel

    EN8 steel material is suitable for the all general engineering applications requiring a higher strength than mild steel such as:

  • General-purpose axles
  • Shafts
  • Gears
  • Bolts and studs
  • Spindles
  • Automotive and general engineering components
  • Other general engineering parts etc.

    • We supply steel grade EN8 to some customers in middle east like UAE, Europe countries like UK and also in Africa like south africa. We will have some EN8 carbon steel promotion at the end of almost every month. Just send emails with detailed requests for EN8 carbon steels price
