Grade Introduction:
EN8 is an unalloyed medium carbon steel grade with reasonable tensile strength. It is normally supplied in the cold drawn or as rolled condition. Tensile properties can vary but are usually between 500-800 N/mm². EN8 is widely used for applications which require better properties than mild steel but does not justify the costs of an alloy steel. EN8 can be flame or induction hardened to produce a good surface hardness with moderate wear resistance. EN8 is available from stock in bar and can be cut to your requirements. We also offer flame cut plates cut to your required sizes and normalized. EN8 plates can be supplied surface ground or precision ground.
 
Grade Application:
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.
 
Equivalent grades:
  • BS 970-1991:080M40
  • AISI/ASTM A29:1038, 1040, 1045
  • DIN Werkstoff No.: 1.0511, 1.1186, 1.1189

Hardness:
 
Heat treatment:
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN8 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities.
 
Hardening:
Heat the component slowly to 820-860°C and allow it to be heated through. Quench in oil or water.
 
Tempering:
Temper the EN8 component immediately after quenching whilst tools are still hand warm. Re-heat the EN8 component to the tempering temperature then soak for one hour per 25 millimeter of total thickness (2 hours minimum) Cool in air. For most applications tempering of EN8 will be between 550-660°C.

Forging Properties:
Preheat the steel carefully, then raise temperature to 1050°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace.
 
Stress Reliving:
 
Normalizing:
Preheat the EN8 steel carefully, then raise temperature to 1050°C for forging. Do not forge below 850°C. After forging cool en8 steel slowly, preferably in a furnace.
 
Annealing:
Heat slowly to 680-710°C, soak well. Cool slowly in the furnace.

Welding:
Modern EN8 bright Mild Steel contains a lot less carbon then it use to, this mean that it is possible to weld pieces up to 18mm thick without preheating using MIG wire (SG2) or a 7018 electrode.
Over 18mm would require a pre-heat of 100°C (212°F) in order to prevent cracking.
Anneal afterwards is recommended to prevent breaking.
