8: 9260 Steel Heat Treatment
Annealing
To produce a coarse to fine spheroidal structure, parts should be austenitized at 1400°F (760°C) and then cooled to 1300°F (705°) at a rate of 10°F/hour or alternately cooled to 1225°F (660°C) and held for 10 hours as an isothermal anneal.
Normalizing
1650°F (900°C) and air cool. This will be an important treatment for this grade.
Hardening
Austenitize and quench in water at 1525-1580°F (830-860°C).
Tempering
880-970ºF (470-520ºC).
