ASTM 4140 alloy steel normalizing

ASTM 4140 alloy steel is normally normalized at 870°C (1600°F) and should be cooled in still air to the specified temperature.

Spheroidizing annealing

For ASTM 4140 alloy steel spheroidizing annealing requires heat treatment to 749°C (1380°F) and then slow cooling to 666°C (1230°F) at 6°C (10°F)/hour or rapid cooling to 675°C (1250°F) for isothermal annealing.

Fully annealed

Heat treated to 845 °C (1555 °F), slow cooled from 755 °C (1390 °F) to 665 °C (1230 °F) at 14 °C (25 °F)/hour, or isothermally annealed to 675 °C (1250 °F) for 5 hours.

Tempering

The tempering temperature of ASTM 4140 alloy steel can be between 204-649 °C (400-1200 °F) after normalizing and oil quenching, and the corresponding Rockwell hardness can be obtained.
