With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
This process is defined as heating a steel to a temperature above the ferrite to austenite transformation temperature, then cooling in air to a temperature well below this transformation temperature. The treatment may be carried out on forged or rolled products as a conditioning treatment prior to final heat treatment.
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.

The process of heat treating is a complicated one if you are hoping to achieve high standards of quality. For the home shop hobbyist, the process is simpler, to an extent. Heat treatment can be split into a number of operations, each which will be separated into a number of steps. The first step is to make a heat treatment furnace.
the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of AISI 4130 alloy steel. Certification
I would suggest you remove a sample and have a metallographic examination performed to verify your heat treatment process. This examination will determine if you had achieved a thru-hardened, quenched and tempered microstructure. I would also confirm the chemical composition of the stock to make sure it was 4130 alloy 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.
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.
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.
Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of AISI 4130 alloy steel.

AISI 4130 Steel Grade Heat Treatment; Annealing of 4130 steels; Annealing of 4130 steel forgings may be carried out by transferring the part straight from the forging operation to a furnace held at a suitable temperature, around 860 C (1575 F) for annealing, holding for a suitable time then furnace cooling.
In the present study, the specific heat treatment applied to the 4130 steel results from the thermal cycle that occurs during thermo-mechanical heat treatment. Therefore, the fatigue behaviour of the 4130 steel will be studied in the as-received API norm condition and after a high temperature high pressure heat treatment. 2.
gases are removed. This melting and refining process path reduces levels of elements such as phosphorus . 4130HW Alloy Steel. Technical Data. 4130HW meets standard 4130 but is modified through tight composition control to improve hardenability and strength in heavier sections.
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. 4130 steel heat treatment process Heat treating 4130 Steel 4130 steel heat treatment process
NORMALIZING HEAT TREATMENT NORMALIZING HEAT TREATMENT FOR STEEL FORGINGS. ThermTech is proud to provide normalizing heat treatment for steel forgings. The process is employed on forged products to homogenize the grain structure, enhance machinability, and improve response to subsequent heat-treating processes. Capability to Run Batch-Type Furnaces
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
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). Hot working of AISI 4130 steel can be done at 816 to 1093C (1500 to 2000F).
Heat treatment. The reason for heat treatment is to prepare the alloy for machining and to enhance 4130 steel properties. There are four main ways to heat treat steel alloy: annealing, normalising, hardening, and tempering. Annealing. Once 4130 steel has been forged into parts, sheets or coils, it may be annealed straightaway.
Chapter 2: Fundamentals of the Heat Treating of Steel / 11 Steel, however, is by far the most widely used alloy and for averygood reason. Among layman, the reason for steels dominance is usually con-sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be rened from ore 4130 steel heat treatment process
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.
The specific annealing cycle is dependent upon the alloy content of the steel, the type of subsequent machining operations and desired surface finish. Frequently, these steels, with the exception of 4340, 50100, 51100, and 52100, are hardened and tempered to a final machinable hardness without preliminary heat treatment. Related Resources:
You can try the heat treatment with the proposed method above, but I have serious doubts on the outcome. It would have been much better to have specified the 4130 structural tubing heat treated and conduct the welding with no post weld thermal treatment.
Consult with a metallurgist or steel supplier for exact temperature ranges and type of atmosphere for the desired steel finish. Support Heat Treatment Guide
