CharacteristicsApplications

42CrMo / 4140 Steel Round Bar 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°C. Hold until uniform. Minimum forging temperature 850°C.Cool slowly in ashes or sand etc.
Annealing Heat to 830°C-850°C.Cool in furnace.
Normalising Heat to 870°C-900°C.Cool in still air.
Stress Relieving Annealed: Heat to 600°C-650°C.Hardened: Heat to 500°C-550°C.Cool in still air.
Hardening Heat to 830°C-880°C. Quench in oil or polymer.
Tempering Heat to 450°C-700°C cool in still air. NB. Tempering within the range 200°C-420°C will result in temper brittleness and should be avoided.
