SAE 2098 Heat Treatments

Solution heat treating at 521°C for all forms.
Aging treatment is mandatory. For all form: Starting temper is T351 or T42, final temper is T851 or T62 (sometimes used to designate final tempers), aging at 160°C for 17-19h. When temper before furnace aging is T4 or T42, the furnace aging treatment may be started immediately after quenching or at any time thereafter.
Full anneal: At 399-427°C, soaking time is minimum 1h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in furnace (furnace cool at 28°C degrees per hour maximum, to 260°C, air cool to room temperature or furnace cool at 28°C degrees per hour maximum, to 232°C, hold at 232°C for 6 hours, furnace or air cool to room temperature). Stress relief: At 333-349°C, soaking time is minimum 0.5h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in air.
Solution Heat Treatment: Temperature 516 to 527°C (960 to 980°F).
