Characteristics
4140 Alloy Steel/SAE 4140 Steel Price is engineering steel supplied
in quenched and tempered conditions. Very good machinability. High
toughness. High creep strength. Repeated impact resistant
capability.
Applications
4140 Alloy Steel/SAE 4140 Steel Price is use to producecomponents
with high requirements on toughness, e.g. gear wheels, pinions,
connecting rods, parts for mechanical engineering .
Heat treatment
ForgingHeat to 1150°C. Hold until uniform. Minimum forging
temperature 850°C.Cool slowly in ashes or sand etc.
AnnealingHeat to 830°C-850°C.Cool in furnace.
NormalisingHeat to 870°C-900°C.Cool in still air.
Stress RelievingAnnealed: Heat to 600°C-650°C.Hardened: Heat to
500°C-550°C.Cool in still air.
