With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.

The SECO/WARWICK Heat Treating Data Book contains information about heat treating metals. This book is not intended as a text, but rather as a collection of frequently used reference data to serve persons interested in heat treating technology. If it saves you time, we feel it will have accomplished its purpose.
I tried to heat treat a piece of 4103 steel .125 thick 6 inches long shaped like a u . I put the piece in the furnace at 1600 degrees for 2 hours (the oven was heat treating 4130 steel - Metal and Metallurgy engineering - Eng-Tips
Heat Treatment Guide. The chart below describes various types of tool steels, their composition and appropriate heat treating applications.
optimum heat-treat response in heavier cross-sections. You find 4140HW in a variety of bar and tubing applications in quenched and tempered conditions. Yield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels. When compared with standard 4140 heat treated to
Forming of AISI 4130 steel can be performed in the annealed condition. Welding of AISI 4130 steel can be performed by all commercial methods. 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).
The axles we made needed heat treatment. The metal can has used engine oil in it. The axles we made needed heat treatment. The metal can has used engine oil in it. best 4130 heat treat chart Heat treating 4130 Steel best 4130 heat treat chart
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.

There ARE some differences in how the steels are hardened and tempered according to the ASM Heat Treaters Guide, Standard Practices and Procedures for Steel. This is a reference that every high tech shop should have if they do or specify heat treating.
The section that I am attempting to harden is approximately 2" x 5" x 18". It was cut from the upright portion of the fork and after heat treating will be welded onto the the tapered flat portion which will protrude from the front with a small section of a horn. My question concerns the hardening heat and quench.
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 heat treat chart
The heat treat you describe is no heat treat at all and will probably have little or no effect on the material. I personally would wonder if your handle bar was made from 4130 in the first place. Or if your original measurements and post measurements for comparison were accurate.
The following chart may be used as a guideline for predicting final hardness. Hold times depend on the size of the heat treat load and furnace size. A guideline is to hold 2X the length of time required for the parts to reach temperature.

Stainless steels are heat-treated based on the stainless steel type and the target end item requirements. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.
The best thing you can do for yourself is heat treat a series of coupons in the steel of your choice and have them Rockwell tested at full-hard, 375F, 400F, 425F, etc. Do 4-5pcs at each tempering heat. Just make sure your part is done as accurately and consistently as you can.(heat, quench, temper, grind to c/u.)
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).
4130 Chromoly MID bottom bracket. Heat-treating is a process that also increases the overall price of the product because its an additional step in the manufacturing process. You will typically find forks, bars and smaller pieces being completely heat-treated with only a few frames being heat-treated completely.
cooling during the heat-treat process. Cold-work Tool Steel. During preheat-ing of cold-work tool steels (A2, D2, etc.), parts are heated to just below the critical austenitizing temperature of about 800 degrees C (1,450 degrees F) long enough to allow the part to be heated evenly. This is necessary because when the part enters
Heat-treatment results (hardness, microstructure, properties) are dependent on such factors as the exact material chemistry, part section thickness and the method of heat treatment. For 4130 steel, the recommended heat treatment  consists of heating to austenitizing temperature, typically 1600F (870C), followed by water quenching.
BCIT millwright students heat 4140 steel to 1650 Deg F to heat treat and harden. The process show the quenching in oil. Be sure to use safety gear when doing this type of work for personal safety.
Through-Hardening Low Alloy Steel Bar 4340 Colour code: Jade (Band) - Marigold Introduction Atlas 4340 is a nominally 1.8 percent Nickel Chromium Molybdenum low alloy steel of high hardenability, with high strength and toughness in relatively large sections achieved with a "quench-and-temper" heat treatment.
We're using it to make the majority of our chassis. We have found a company that will probably help us heat treat the frame after, but at this point we are sort of venturing into new territory for us. Anybody ever built a frame from 4130 and gotten it heat treated? What strength were you looking for? how did it last?
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.
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability and machinability. Type 4130 steel should be forged between 2250 and 1750 F (1230 and 950 C.).

A Simplified Guide to Heat Treating Tool Steels Quenching Quenching must be done promptly in the medium prescribed for the grade with the exceptions discussed further. Actually, Water Hardening steels are properly quenched in brine. A pound of salt to a gallon of water is a good guide.
HEAT TREATMENT OF TOOL STEEL 5 Uddeholm Dievar, hardened structure. Austenite has a higher solubility limit for carbon and alloying elements, and the carbides will dissolve into the matrix to some extent. In this way the matrix acquires an alloying con-tent of carbide-forming elements that gives the hardening effect, without becoming coarse best 4130 heat treat chart
