4340 is a steel type that has medium carbon and low alloy steel levels. This particular grade is popular due to the balance that it has in terms of strength and toughness. You usually get supplied with 4340 steel in the tempered and the hardened condition. This AISI 4140 Chrome-Molybdenum High Tensile Steel

  • IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.
