Physical Properties

Temperature	20°C	400°C	600°C
Density g/cm3	8	7.9	7.9
Modulus of elasticity kN/mm²	225	200	180
Thermal expansion ratio per °C	–	11.5×10 -6	11.8×10 -6
Thermal conductivity W/m°C	24	28	27
Speciﬁc heat J/kg°C	420	510	600

Stress Relieving

Heat to 650 / 700 C. Hold for 2 – 4 hours and furnace cool.

Hardening

Heat slowly to 101 O / 1060° C and oil quench. Smaller sections can be air cooled. As quenched hardness in the range of Rockwell “C” 60 / 61 is possible.

Tempering

Tempering 440C in the range of 180 / 230° C is recommended to develop full -working hardness in the range of Rockwell “Cn 57 I 59.
