Preheating : As P20 is sold in a pre-hardened position, hardening heat treatment is not needed. After machining and intermittently during pottery, the steel must be thermally stress relieved by heating to 900ºF (482ºC), equalizing and holding for one hour per inch (25.4mm) of width, and cooling in air to ambient heat.
In those rare circumstances where the steel must be re-hardened, the steel must first be annealed prior to solidification.
Austenitizing (High Heat) : Heat rapidly from the preheat to 1550ºF (843°C). Soak for 30 minutes for first inch (25.4mm) of breadth, plus 15 minutes for each additional inch (25.4mm).
Quenching : Pressurized gas, or interrupted oil to 150-125ºF
For oil, quench until black, at about 900°F (482°C), then cool in
still air to 150-125°F (66-51°C).
Tempering : Temper immediately after quenching or cryogenic method. Hold at the temperature for 1 hour per inch (25.4mm) of density, 2 hours particle, then air cool to ambient heat. Tempering temperatures and hardness are given in chart over.
