TITLE(s): HEAT TREATER I (heat treating)
Controls heat-treating furnaces, baths and quenching equipment to alter physical and chemical
properties of metal objects, using specifications and methods of controlled heating and cooling,
such as hardening, tempering, annealing, case-hardening, and normalizing: Determines temperature and
time of heating cycle, and type and temperature of baths and quenching medium to attain specified
hardness, toughness, and ductility of parts, using standard heat-treating charts, and utilizing
knowledge of heat-treating methods, equipment, and properties of metals. Adjusts furnace controls
and observes pyrometer to bring furnace to prescribed temperature. Loads parts into furnace. Removes
parts after prescribed time and quenches parts in water, oil, brine, or other bath, or allows parts
to cool in air. May test hardness of parts [HARDNESS INSPECTOR (heat treating)]. May set up and
operate die-quenching machine to prevent parts from warping. May set up and operate electronic
induction equipment to heat objects [INDUCTION-MACHINE SETTER (heat treating)]. May align warped
fuel elements, containing radioactive uranium, using hydraulic ram straightener.
