CHEMICAL COMPOSITION (Typical Analysis in %)
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.
Annealing Heat slowly to 680-710°C, soak well. Cool slowly in the furnace.
Hardening Heat the component slowly to 820-860°C and allow it to be heated through. Quench in oil or water.
EN8 is widely used for many general engineering applications
Typical applications include shafts, studs, bolts, connecting rods, screws, rollers
raise temperature to 1050°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace
EN8 steel grade belongs to the standard of BS 970-1955, which is a standard for wrought steel for mechanical and allied engineering purpose. In BS 970 standards, there are some other common steel grades, like EN9, EN19, EN24, EN36 etc.
