Grade Introduction:
EN9 is a medium carbon steel grade commonly supplied in the as rolled condition. It can be flame or induction hardened to produce a high surface hardness with excellent wear resistance for a carbon steel grade. EN9 bar is available in full lengths or can be cut to your requirements. EN9 flame cut steel plates can be supplied cut to your required sizes and normalized. Flame cut plates can be supplied Lumsden ground or precision ground.
 
Grade Application:
EN9 is used commonly for many general engineering applications. Typical applications include, shafts, axes, knives, bushes, crankshafts, screws, sickles, wood working drills and hammers.

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 EN9 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities.
 
Hardening:
Heat slowly to 820-840°C and allow it to be heated through. Quench in oil, brine or water.
 
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 millimeter of total thickness (2 hours minimum) Cool in air. For most applications tempering of EN9 will be between 550-660°C.

Thermal Properties:
 
Forging Properties:
Preheat the component carefully, then raise the temperature to 1100°C for forging. Do not forge below 850°C. After forging cool slowly, preferably in a furnace.
 
Stress Reliving:
 
Normalizing:
The normalizing temperature range for this grade is typically 820-880ºC, followed by cooling in still air.
 
Annealing:
Heat slowly to 680-710°C, soak well. Cool slowly in the furnace.
