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 produce components 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. |
| Normalizing | 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. |
