AISI 4140 steel grade is a versatile steel grade. 4140 material is widely used in a lots of industrial fields. It is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. ASTM 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI steel 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.
Here we list 15 common applications for 4140 steels material:
- Shaft
2. Crankshaft
3.Bolt
4.Machinery Parts
5. Gear
6. Milling Spindle
7. Nut
8. Slide
9. Steel Collet
10.Steel Converyor and Roll
11. Steel Coupling
12. Drill Collar
13. Steel Ejector
14. Steel Piston Rod
15. Steel Stub
