Tempering:P20 tool steels are tempered at 482-593°C (900 to 1100°F) for a Rockwell C hardness of 28 to 34.
Annealing:Annealing takes place at 760-788°C (1400 to 1450°F) and then the steels are cooled slowly in the furnace at a temperature less than 4°C (40°F) per hour.
Cold Working:P20 tool steels are capable of being readily cold worked by using conventional tooling methods with the alloy in the annealed condition.
Welding:Conventional methods are used for welding of P20 tool steels.
Forging:P20 tool steels are forged at 1093°C (2000°F) down to 899°C (1650°F). Forging below 871°C (1600°F) is not recommended for these steels.
Forming:P20 tool steels can be readily formed by conventional methods in the annealed condition.
Machinability:P20 tool steels have excellent machinability at about 80% that of water hardening steels.
Heat Treatment:P20 tool steels are heated to 871-899°C (1600-1650°F) in the carburizing medium during the carburizing process. After being carburized, these steels are heated to 816-871°C (1500-1600°F) in order to be hardened and then held for 15 minutes and finally oil quenched.
Applications:P20 tool steels are used for low-temperature applications that include injection molds and die casting dies.
