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. Is 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 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 What are the uses of SAE 4340 steel?What are the uses of SAE 4340 steel?

IH8MUD ForumJan 23, 2005In fact, for their Dana60 axles they went from 4340 material on their 2nd generation axles to 4140 on their 3rd gen. axles. Both PIG and Bobby Long feel 4340 makes a better axle material, and most posts about Toy truck rear axle shafts in POR are dissing All Pro's 4140 axles (made by Superior) and favor PIG's new 4340 although apparently out of 4140 4340 ut testing steel shaft
We use 4140 in Rear shaft applications, as 4140 we can heat treat efficiently while maintaining high surface hardness which is important for the non-steering application. In front axle kits, we use 4340 chromoly, stronger still, and even more complicated on proper heat treatment.Castle Metals SiteUltrasonic testing. Ultrasonic metal testing, or UT testing, is a nondestructive test (NDT) which uses a straight beam to detect internal porosity and cracks. UT can also be performed via a shear wave to detect longitudinal surface cracks.

It's expensive than 4140 and the availability is also not as good as 4140 steel. Since the two steel grades have a lot in common, it depends on what applications you want use such materials for. And we could supply both. A. atomicjoe23 Well-Known Member.

This also applies to AISI 4140 and 4340. We will not be discussing the metallurgical properties of 4140 or trying to explain what happens to its microstructure when it cools too rapidly, just remember that the key is to control our cooling rate.
hardness of 4140 steel. The most common test for studying these effects is the Jominy End Quench test. In this test a 140mm long and 25.4 mm in diameter sample is heated into the austenite range for selected temperatures and times and water spray quenched at one end, producing a varying cooling rate across the sample.Mirraloy&TGP 4140 Steel Associated Steel CorporationMirraloy&TGP (4140/4150 Mod) Turned Ground & Polished, Alloy Shaft. Mirraloy is a modified 4140/4150 steel, turned ground and polished shaft. Typical hardness is 269/341 BHN. This chromium and molybdenum based alloy is electric furnace melt, vacuum degassed, stress relieved, and People also askWhat 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 shaft

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 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.V/5r0 OFtIIO7'In an earlier study, the crack arrest fracture toughness of 4140 and 4340 steel was measured as a function of yield strength and test temperature (4) The yield strength was varied over the range of 140 to 180 ksi, and the temperature from -65 to +165F, the ranges of most interest for armament materials.
