With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
For 4130 steel, the recommended heat treatment  consists of heating to austenitizing temperature, typically 1600F (870C), followed by water quenching. Water quenching will achieve a higher as-quenched hardness than oil quenching.

Heat Treatment - AISI 4130 steel is heated at 871C (1600F) and then quenched in oil. This steel is usually heat-treated at temperatures ranging from 899 to 927C (1650 to 1700F). Forging of AISI 4130 steel can be performed at 954 to 1204C (1750 to 2200F).
Reynolds makes a 4130 called Reynolds 525. It's a general all-purpose tube - less expensive than 853. The 4130 is a code of the American Iron & Steel Institute and defines the approximate chemical composition of the steel. The "41" denotesbest 4130 steel heat treatment

Forging. Type 4130 steel should be forged between 2250 and 1750 F (1230 and 950 C.) The lower the finishing temperature from forging, the finer will be the grain size. If the alloy is forged at too low a temperature, there is a risk of the formation of a non-uniform structure in certain areas of the forged part,best 4130 steel heat treatment
For spheroidizing annealing of 4130 alloy steel, it needs heat treated to 749 C (1380 F), followed by slowly cooling to 666 C (1230 F) at a rate of 6 C (10 F)/hour, or rapid cooling to 675 C for 8 hours isothermal annealing. Full Annealing
RE: heat treating 4130 steel. 23 Feb 05 14:25. Your austenitizing temperature of 1600 deg F is ok, the furnace soak at temperature should only be 30 minutes ( at 1600 deg F for 30 minutes) not 2 hours. Immediately quench in oil (this is most important to perform as rapidly as possible).

Heat tends to even out. If you try to heat treat steel without something to keep the heat in, it will be very difficult to maintain a temperature, and a lot of the heat will get wasted. That is why we will build a furnace chamber out of bricks. Try and find bricks that are rated for the highest heat resistance. Lay out a layer of bricks flat best 4130 steel heat treatment
Heat-Treating is a term that goes hand in hand with 4130 chromoly very frequently in BMX. What is heat-treating exactly? It is a process where extreme heating and / or cooling is applied to the chromoly to alter its properties that can change hardness, strength, toughness, ductility and elasticity in the material.
My camera died before we tempered them and did some testing. Ill try to get some more footage soon.
This article provides some best practices for selecting the proper filler metal for welding 4130 heat-treatable low-alloy steel, along with recommendations for pre- and post-weld heating. Because of its high hardenability, 4130 steel responds well to heat treating, which offers advantages for many applications.
Description: Universal 4130 is a heat treatable low alloy steel for the welding of SAE 4100 series steels.Some of these steels, the higher carbon grades, will require a preheat of 300 to 350 degrees F.
4140HW Alloy Steel Technical Data 4140HW meets AISI4140 standards and has improved hardenability and strength in heavier cross-sections. Alloy Description TimkenSteels 4140HW grade is a fine-grained, low-alloy steel that offers optimum heat-treat response in heavier cross-sections. You find 4140HW in a
AISI 4130 steel is also good in weldability, and the 4130 alloy may be welded by any commercial method. The material may require a post-weld stress relief heat treatment in certain instances. Low-hydrogen electrodes are recommended together with preheat at 150 260 C (300 500 F) to be maintained during welding, Cool slowly and best 4130 steel heat treatment
Heat Treatment Heating at 1600 F followed by an oil quench will harden the 4130 alloy. For best results a normalizing pre-hardening heat treatment may be used at 1650 to 1700 F followed by the 1600 F soak and oil quench. Forging Forge at 2200 F maximum down to 1750 F. Hot Working 4130 in the annealed condition has excellent ductility.
Consult with a metallurgist or steel supplier for exact temperature ranges and type of atmosphere for the desired steel finish. Support Heat Treatment Guide
The heat treating process is much more forgiving with 4130 than with 1050 carbon steel. The yield strength and ductility are better at higher hardnesses than with 1050. In the USA 4130 is currently easier to purchase in small amounts than 1050.
The heat treating information shown represents typical procedures and hardnesses for many applications. Other procedures and hardnesses may be available. See individual data sections for more specific information.
I need to make .125 x 4130 straps for a spar connection. I am looking for information on the deformation of 4130 after being heat treated to 125000psi. If the part were drilled before treating, would the holes match after heat treating?
Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc. The most common application is metallurgical but heat treatment of metals can also be used in the manufacture of glass, aluminum, steel and many more materials.
AISI 4130 Steel, normalized at 870C (1600F) best 4130 steel heat treatment Flexibility afforded by heat treatment options allows it to attain a range of toughness and strength values. Good best 4130 steel heat treatment
SAE AISI 4140 Alloy Steel. 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.

Stormcrow, the steel used and the heat treat are somewhat shape dependent on power hammer dies. 1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use.
