WebPrecipitation hardening alloys are tempered as well. Unless otherwise specified, the minimum hold time at the temperature is generally one hour per inch of cross section after the load has reached set point temperature. Tempering equipment should have tight temperature uniformity, typically ± 10°F or in some instances ± 15ºF is acceptable. WebSep 16, 2024 · Time and number of cycles does effect the hardness, but not nearly as much as temperature. If you temper two times at 400 and put it in a 3rd time, the 3rd temper will drop it again, but only perhaps 1/4 point. It's small enough that for most practical purposes it can be ignored, but it is there. classical theory of employment and output pdf
