EN9 En Series Steel

Applications:

• EN9 is used commonly for many general engineering applications.
• Typical applications include, shafts, axes, knives, bushes, crankshafts, screws, sickles, wood working drills and hammers.

Annealing:
Heat the steel slowly to 680-710°C, soak well.
Cool slowly in the furnace.

Hardening:

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

Tempering:

• Temper the EN9 steel component immediately after quenching whilst 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 EN9 will be between 550-660°C.

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 EN9 steel 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 EN9 carbon steel.
