Chemical Composition(%)

C	Si	Mn	P	S	Cr	W	V
1.15-1.25	0.15-0.30	0.20-0.35	0.035 max	0.035 max	0.15-0.25	0.90-1.10	0.07-0.12

HEAT TREATMENT:

SOFT ANNEALING: Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.

STRESS RELIEVING:Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

HARDENING:Harden from a temperature of 760-820oC, 800-840oC followed by water or oil quenching. Hardness after quenching is 64-66 HRC.

TEMPERING: Tempering temperature: 150-250oC. See the data bellow.

Tempering Temperature	Hardness(HRC)
100oC	66
200oC	65
300oC	59
400oC	53

Mill′s test certificate:
