Thermal conductivity [W/m.K]: 33.5, 32 (500oC), 31 (700oC)
Electric resistivity [Ohm mm2/m]: 0.33
Specific heat capacity[J/g.K]: 0.46
Coefficient of Linear Thermal Expansion 10-6 oC-1
| 20-100oC | 20-200oC | 20-300oC | 20-400oC | 20-500oC |

Soft Annealing
Heat to 710-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 223.
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 780-820oC, 800-840oC followed by water or oil quenching. Hardness after quenching is 64-66, 64-66 HRC.
Tempering
Tempering temperature: 100-400oC.
Tempering Temperature (oC) vs. Hardness (HRC)
| 100oC | 200oC | 300oC | 400oC | 450oC |
| 64 | 63 | 59 | 54 | 47 |
