But it is the mark of a craftsman to be able to tell temperature by eye, if only to validate the instrumentation (or suspect it!) If the austenitic steel is cooled slowly (the process known as annealing), it will return to the pearlite structure. The tempering temperature is dependent on what hardness is required for the component. Our family machine shop used quite a bit of this material to avoid heat treating parts. The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. When the heat takes on a white color, forging with high carbon steel can be difficult. After a metal has been soaked, it must be returned to room temperature to complete the heat-treating process. If steel is heated in an oxidizing atmosphere - like air - a film of oxide forms on the surface and the color changes as the temperature increases. I heard from some coworkers that there is a chart for steel that gives you a temperature range in the part based on its color. The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. F.
