  • Form of Supply
  • Suppliers of round bar we can offer diameters in EN47 sawn to your required lengths as 1 offs or multiple cut pieces. Ground steel bar can be supplied, providing a high quality precision ground spring steel bar to tight tolerances.

Diameter Applications : EN47 is used widely in the motor vehicle industry and many general engineering applications. Suitable for applications that require high tensile strength and toughness. Typical applications include crankshafts, steering knuckles, gears, spindles and pumps.

Forging : Preheat the steel carefully, then raise temperature to 1050°C for forging. Do not forge below 840°C. After forging EN47 spring steel cool slowly, preferably in a furnace.

Annealing : Heat slowly to 820-840°C, soak well. Cool slowly in the furnace.

Hardening : Heat slowly to 650-700°C and thoroughly soak. Continue to heat the steel to the final hardening temperature of 830-860°C and allow the component to be heated through. Quench in oil.

Tempering : Temper the EN47 spring steel component immediately after quenching whilst tools are still hand warm. Re-heat to the tempering temperature then soak for one hour per 25 millimetre of total thickness (2 hours minimum) Cool in air. For most applications tempering of this grade will be between 400-600°C.

Heat Treatment : Heat treatment temperatures, including rate of heating, cooling and soaking times etc. will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of EN47.
