1. The duration of a heat treatment.
   • 2000, Sandra J. Midea, Heat Treating, Including Steel Heat Treating In the New Millennium, page 160:

     When concentrator is removed and the coil current is the same, the induced power is much less and the heat time must be increased from 2.9 to 5.2 seconds (Figure 11).

   • 2006, George E. Totten, Steel Heat Treatment: Equipment and Process Design, page 349:

     This includes energy input into the part, quench flow rate, temperature, quench pressure, and heat time.

   • 2011, Valery Rudnev, “Recent Inventions and Innovations in Induction Hardening of Gears and Gear-like Components”, in ‎B. Lynn Ferguson, ‎R. Jones, editor, Heat Treating 2011, page 179:

     A high power density in combination with the relatively short heat time generally results in a shallow pattern, while a low power density and extended heat time produces a deep pattern with wide transition zones.

2. The total amount of time from the moment when scrap is charged to an empty electric arc furnace and ending when the electric arc furnace tap is completed.
