Heat Treating Information:
Preheat: Heat to 1400° and equalize.

Austenitize: Ramp to 1900-2000°F and hold at temperature for 30-60 minutes. Oil or plate or air quench to below 125°F.

Temper: Twice at 400-1200°F for 2 hours minimum each time. Tempering at 800-1100°F will result in a minor reduction in both corrosion resistance and toughness.

Cryogenic Treating: After the first temper may improve long term dimensional stability by transforming retained austenite. Cryogenic treatment must be followed by a temper.
