Characteristics
4140 steel sheet in quenched and tempered conditions. Very good machinability. High toughness. High creep strength. Repeated i***ct resistant capability.
Applications
AISI 4140 Steel Sheet is used to producecomponents with high requirements on toughness, e.g. gear wheels, pinions, connecting rods, parts for mechanical engineering .
Heat treatment
Forging Heat to 1150℃. Hold until uniform. Minimum forging temperature 850℃.Cool slowly in ashes or sand etc.
Annealing Heat to 830℃-850℃.Cool in furnace.
Normalising Heat to 870℃-900℃.Cool in still air.
Stress Relieving Annealed: Heat to 600℃-650℃.Hardened: Heat to 500℃-550℃.Cool in still air.
Hardening Heat to 830℃-880℃. Quench in oil or polymer.
Tempering Heat to 450℃-700℃ cool in still air. NB. Tempering within the range 200℃-420℃ will result in temper brittleness and should be avoided.
