(Compare Fig. 11 with Figs. 10 and 12.) This is a result of the fact that even at super-transition temperatures, the toughness is moderate, e.g., all the 160 ksi yield strength speci-SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent 4140 4340 ut testing steel shaftForging 4340 steel is usually forged at a temperature of 1065 to 1230 °C (1950 to 2250 °F); after forging, the parts can be air-cooled in a dry place, or preferably with a furnace. Welding of AISI 4340 Steel. AISI 4340 steel has good weldability. It can be easily gas or arc welded, but electrodes of the same composition should be used.
Recommended corrosion protection finish for 4340 steel
Apr 12, 2011Recommended corrosion protection finish for 4340 steel. A discussion started in 2011 but continuing through 2018. April 12, 2011. Q. I am designing a tie-rod, a 1 meter long 14 mm diameter rod with a 30 mm threaded section at each end. The material is is 4340 steel What 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 4140 4340 ut testing steel shaftMirraloy&TGP 4140 Steel Associated Steel CorporationMirraloy&TGP (4140/4150 Mod) Turned Ground & Polished, Alloy Shaft.

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 51 for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I).Hardness of Heat Treated 4140 - Metal and Metallurgy 4140 4340 ut testing steel shaft
Fabricating and Repairing 4130 and 4140 Steels in Heavy 4140 4340 ut testing steel shaft
Because of their high hardenability, 4130 and 4140 steels are commonly used for shafts, gears and forgings. But they are also more susceptible to cracking, so its important to choose the right filler metal that matches the chemistry of the base metal for components to be annealed, normalized, or quench and tempered after welding.
