WebbNormally, once the whole of the workpiece is at the annealing temperature, the annealing time should be between 10 and 30 minutes, depending upon the section thickness. The shorter times within this range should be used for thin sheet components. The longer times should be used for thick (heavier) sections. computer alt key stuckWebbThe difference between the two processes relate to the temperatures and cooling rates, with tempering happening at lower temperatures but with faster cooling times.
