If you must use 6011/7024 [you may have a small AC stick welder] give it a try[weld while still hot from forging, and give the weld a little hammer test after cooling, to be sure it will hold up for service.What is the tensile strength of 4140?This means that despite being physically and mechanically stronger, 4140 is not very heavy. One of the most outstanding properties of this metal is the high tensile strength. The tensile strength of this metal can be as high as 95,000 PSI. This means that this metal cannot break easily even when subjected to some kind of a heavy load.See all results for this question
What is the difference between 4140 4340 material?
TVP (Materials) 9 Jul 02 11:54 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.See all results for this questionWhat is the best welder for steel?View the Best Tig Welder for the Money, BelowAHP AlphaTIG 200DX.
