    Are you Tig welding the 4140. Preheating to 400F - 600F and using 4140 filler is where to start. I have welded a fair amount of 4140 using Cronatig 340T filler (Cronatron Welding Systems from Lawson Products (www.lawsonproducts.com).I haven't had to mag particle test the welds so I can't help you there but I have had no issues with weld failures.

  14. 4140 vs 4340 - Material engineering general discussion ...

    Jul 09, 2002 · 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.Some results are removed in response to a notice of local law requirement.

    Cold Working The alloy readily cold works in the annealed condition by conventional methods. Annealing Annealing is done at 1600 F followed by slow furnace cooling. Aging Not applicable to this alloy. Tempering Tempering temperatures range from 400 F to 1200 F depending upon the hardness level desired. The lower the tempering temperature the greater the hardness of the alloy.
