results for this questionIs there a maximum hardness level for 4140?Is there a maximum hardness level for 4140?The maximum hardness that can be obtained in any steel depends on carbon content.The section size in which maximum hardness can be obtained depends on alloy content.4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).Hardness of Heat Treated 4140 - Metal and Metallurgy results for this questionWhat is the difference between 4140 4340 material?What is the difference between 4140 4340 material?There is a huge difference between these two alloys chemically,namely the nickel content 4140 nominally has no Ni and 4340 contains between 1.65 and 2.00 % Ni.This contributes to substantial differences in hardenability and fracture toughness,and also has a positive effect on distortion during quenching and corrosion resistance.4140 vs 4340 - Material engineering general discussion results for this questionWhat is the tensile strength of 4140 steel?What is the tensile strength of 4140 steel?There are several important mechanical properties of AISI4140,including Tensile Strength AISI 4140 steel typically has a target ultimate tensile strength of around 95,000 psi.Reference metalsupermarkets/grade-guide-4140-steel/ results for this questionFeedback4140 HIGH TENSILE STEEL - Engineering Steels
Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding.4140 is used extensively in most industry sectors for a wide range of applications such as Adapters,Arbors,Axle Shafts,Bolts,Crankshafts,Connection Rods,Chuck Bodies,Collets,Conveyor Pins Rolls,Ejector
