IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingNitridingTemperingFlame and Induction HardeningAISI 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 sWhat is the hardness of 4140 steel? - AskingLot4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T). What is the hardness of 4140 annealed?
AISI 4140 QT/SR TGP Alloy Round Bar Manufacturer AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840-875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5)Tempering

Metallurgical Investigation of the Effects of Double Tempering on the Hardness, Impact Toughness and Microstructure of AISI 4140 Steel. The second goal of this project is to incorporate the given results from single and double tempering in the design of a double-
Handbook:Everything You Should Know About 4140 SteelHow is 4140 Steel Annealed Hardened and Tampered? Before 4140 steel is ready for use, it is usually subjected through these three processes; annealing hardening and tampering. The purpose of these processes is to enhance the physical and mechanical properties of this steel. 4140 steel is annealed at 872°C which is equivalent to 1600°F.
