GTFiji (Mechanical) (OP) 14 Mar 06 14:25. I am looking at these two materials (4140 vs 4340) for my application, as suggested by users of this forum. I have a 62" octagonal bar (1" flat to flat) heat treated to a minimum of 150k UTS. I need to machine a square bar to my shape and then heat treat.
- 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. The AISI 4140 cold finished annealed chromium-molybdenun alloy SAE AISI 4140 Steel Properties, Material Heat Treatment Dec 14, 2019 · SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature. 4140 Steel Uses.
