What is the basic difference between oil-quench and water quench when performing a quench & temper of small diameter (under 3 ) 4140 steel bars ? 4140 oil quench vs water quench - Material engineering general discussion - Eng-Tips
It has the highest strength compared to the other variants of SAE-AISI 4140 steel. The graph bars on the material properties cards below compare quenched and tempered SAE-AISI 4140 to: SAE-AISI wrought steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set.
quenching of AISI 4140 steel C-rings in oil and water, which is compared with experimental data. The severity of the water quenching was responsible for the larger simulated distortion when compared with the oil quenching process. Water quenched C-ring crack and the applied residual stresses during the cooling stage were investigated.

Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel.
Thread: Hardening 4140 steel. Once to temperature hold there for about 20 minutes per inch of thickness. The longer it's above critical the more decarburization you'll get, for more then an hour I'd look at an inert environment. If it's really thick you'll want a big quench tank - I warm my 5 gallon from 50 to 100 degF with a 6 pound chunk of steel,4140 steel water quenched supplier
You will notice that they recommend quenching in oil water or polymer as required. One thing that is stated by most other steel suppliers is to avoid where possible tempering 4140 in the regions between approx 200degC and 450/475degC (392F to 887F) as 4140 and also 4340 have a tendancy to lose ductility and become temper brittle in these ranges.
Smaller sections of 4140 might be quenched in oil, heavier sections in water. Tempering is carried out to relieve stresses from the hardening process, but primarily to obtain the required mechanical properties. The actual tempering temperature will be chosen to meet the required properties, and in many cases will be a matter of trial and error.

SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.
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.
quenching of AISI 4140 steel C-rings in oil and water. The severity of the water quenching was responsible for the larger distortion when compared to the oil water quenching process. The simulations are carried out with coupled analysis of heat transfer, deformation mechanics and phase transformations. In addition,

I usually send my heat treating out, but in the little bit I have done with a few types of steel, I think W1 drill rod is the easiest. Heat 'er up as fast as you can, and stick it in the cold water quench. However, I don't think that heat technique works quite as well for 4140, because it is slower to make the phase changes.

4340 ,water quenching was a learning experience. Avoid water as quench media, try polymer quench or migrate to oil quench and have peace of mind. I'm just one step away from being rich, all I need now is money. ( read somewhere on the internet)
4140 can be quenched in oil or water. Such a big pieces is going to have trouble in a normal knife maker's quench setup and will need quite a bit of fluid and won't quench well in 5 gallons of oil. That will catch on fire and be under quenched.
