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 4340 steel plate spot(PDF) Experimental Investigation of Laser Surface 4340 steel plate spot
