Characteristic:


42CrMo Alloy Steel / GB 42CrMo / Tool Steel 42CrMo is of engineering steel supplied in quenched and tempered conditions. Very good machinability. High toughness. High creep strength. Repeated impact resistant capability.



Applications:

42CrMo Alloy Steel / GB 42CrMo / Tool Steel 42CrMo 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.
