EN47 Spring Steel

EN47 is a tough oil quenching spring steel which, when heat treated, offers good wear resistance.

TYPICAL ANALYSIS
C.	Mn.	Cr.	V.
0.50%	0.75%	1.00%	0.15%

Forging:
Forge at 1050°C. Do not work this steel when it has fallen below 840°C.

Annealing:
Slow furnace cool from 840°/860°C.

Hardening:
Pre heat slowly to 650/700°C and thoroughly soak. Continue heating to the final hardening temperature of 850/870°C and allow the component to be heated through. Quench in oil.

Tempering:
Temper immediately after quenching whilst tools are still hand warm. Re-heat to the tempering temperature, soak for one hour per 25 millimetre of total thickness, 2 hours minimum, then cool in air. For most applications tempering will be between 400°/600°C.
