Heat treat
- Preheat
- Heat to 1,500-1,550°F. Equalize temperature.
- Austenitize
- Following preheat, heat material rapidly. a) For maximum wear resistance austenitize at 2,100°F, soak 15 minutes, and quench. b) For the best combination of toughness and wear resistance, austenitize at 1,875-1,950°F, soak 30 minutes, and quench. c) For maximum toughness austenitize at 1,800°F, soak 30 minutes, and quench.
- Quench
- Plate, air or positive pressure quench (4 bar minimum), or medium oil quench to about 900°F, then air cool to below 125°F.
- Temper
- Immediately after quenching, temper three times (two times minimum). Do not temper below 1,000°F.
- Cryogenic Treating
- May improve long term dimensional stability by transforming retained austenite. Any cryogenic treatment must be followed by a temper.
Steel certs
- Look up the chemical composition cert for your bar with the three red letters stamped on it.
