Forged of P20 Mold Steel Material
Forging of this steel should be forged at 1093°C (2000°F) down to 899°C (1650°F). Forging below 871°C (1600°F) is not recommended for these steels.
P20 Tool Steels Heat Treatment
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.
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.
P20 Alloy Steel Uses
P20 tool steels are used for low temperature applications that include injection molds and die casting dies.
