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. The AISI 4140 cold finished annealed chromium-molybdenun alloy 4140 stainless - Steel Material SupplierJun 26, 2019 · This added energy and corrosion resistance signifies that CrMo steel is used when the energy offered by gentle carbon metal isnt sufficient. These benefits give chrome moly added reliability, which is why its utilized in so many various applications. AISI 4140 alloy metal may be welded utilizing all standard techniques. AISI 4140 Engineering Steel Steel EThe 41xx family of steel include chromium and molybdenum and are often referred to as chromoly steel or chrome-moly. Chromoly steels have an excellent strength to weight ratio but do not contain sufficient quantities to provide the levels of corrosion resistance found in stainless steels.
