It is known that structural steel begins to soften around 425°C and loses about half of its strength at 650°C.This is why steel is stress relieved in this temperature range. So, the range will be around 500 to 600 degrees celcious temperature.
Below absolute zero and above to temperature of about 1800°F for 310 SS .(working pressure)
Please refer iron-carbon equilibrium diagram.
Mild steel starts lossing its ductility with more than 0.83% carbon content.

its fatigue limit.
Over a very large number of cycles 10^9 kind of range steels will tend to exhibit a strength of 1/3 of their non fatigue value due propagation of its impurities.
This is unlike a material such as aluminium which will keep on declining in strength.
