EN24 is a high quality, high tensile, alloy steel . Usually supplied readily machineable in 'T' condition, it combines high

tensile strength, shock resistance, good ductility and resistance to wear. EN24 is available from stock in round bar, flat bar

and plate.

Hardening:

Heat uniformly to 823/850°C until heated through. Quench in oil.

Tempering:

Heat uniformly and thoroughly at the selected tempering temperature, up to 660°C and hold at heat for two hours per inch of

total thickness. Tempering between 250-375°C in not recommended as this can seriously reduce the steels impact value.

Stress Relieving:

Heat slowly to 650-670°C, soak well before cooling the EN24 tool in a furnace or in air.
