The heat treatment process involves the controlled application of heat to alter the physical (and sometimes, chemical) properties of a metal. While we do not perform heat treating as part of our services at Metal Cutting, we are mindful of the dimension-altering effects of heat treating metal.
4140/42 and 4130 Mechanical Tubing are medium carbon alloy grades, which are widely used for many general-purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness, ductility, and strength.
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.
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.

We are planning on having them heated treated, but I was told that once they are heated treated you can no longer weld to them. , buy cs api 5l gr b So, back to the heat treatment process names being used , buy cs api 5l gr b
1. what was your heat treat process? Pre-heat, soak, quench, temper? 2. Do you have any sharp inside corners on your part? 3. Size of the part with min and max cross-sectional areas? 4. 45 Rc is on the high end for 4130 hardness. Most of the time, it's drawn to around 28-32 Rc. I don't know about , buy cs api 5l gr b
The process uses such a high temperature in order to create the conditions for transformation from ferrite to austenite, and is then air cooled to finish. Hardening. The objective of a hardening heat treatment is obviously to alter 4130 steel properties by increasing the hardness, but it also increases the tensile strength and brittleness of , buy cs api 5l gr b

Technical Data. 4130HW meets standard 4130 but is modified through tight composition control to improve
Alloy Steel Round Bar 4130 offers good strength and weldability without compromising steel abrasion or impact resistance. This material comes in the normalized condition and doesn't require further heat treatment. It is typically used in structural applications, gears, fasteners, and aircraft exteriors.
4130 / (EN) 25CrMo4 In my opinion 4130 looks to be the best material for SCA, BotN, and ACL armour in all area except rust resistance. 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.
When you buy 4140, it is annealed and has a Rockwell hardness of 28-30( 135,000 Tensile~) To heat treat 4140, You need to heat it to 1550 F. and hold it at that temperature for one hour per inch of thickness. So if your part is 1/2 thick, then a half hour is good.
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.
The process of heat treatment involves the use of heating or cooling, usually to extreme temperatures to achieve the desired result. It is a very important manufacturing processes that can not only help the manufacturing process but can also improve product, its performance, and its characteristics in many ways.
relief heat treatment cannot be carried out immediately upon completion of welding, the temperature of the completed weldment can be raised to approximately 400C (750F), which is the vicinity of the bainite knee for 4130 and most other heat - treatable alloy steels .
In this video we give some basis on how to get some 4140 alloy steel hardened and then temper to different hardness, we will perform our test using a Rockwell hardness tester. This is a basic , buy cs api 5l gr b
Heat treating (or heat treatment) is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.The most common application is metallurgical.Heat treatments are also used in the manufacture of many other materials, such as glass.Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve , buy cs api 5l gr b

Heat Treating Data Sheet for 4130; 4130H, Chromium-molybdenum alloy steel, including information regarding Hardness, Chemical composition, Microstructure, Heat treating, Forming or forging.
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.
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).
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.).
AISI 4130 steel is usually supplied ready heat treated with a hardness of 18-22HRC. If further heat treatment is required annealed AISI 4130 should be heated slowly to 870-890C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
Because of its excellent combination of high toughness and resistance to thermal fatigue cracking (also known as heat checking) H13 is used for more hot work tooling applications than any other tool steel. Because of its high toughness and very good stability in heat treatment, H13 is also used in a variety of cold work tooling applications.
Since polymer quenching is the most critical component of the heat treatment quench and temper process with respect to final mechanical properties, ThermTech has made huge investments in our quench systems. All parameters of quenching are controlled, temperature, concentration and agitation. , buy cs api 5l gr b Polymer Quenching 4130 Steel .
Are you heat treating to achieve original strength or for post weld heat treatment? If you're post weld heat treating because of welding, I would not recommend it because of concerns with distortion. The 4130 has decent weldability and with your stated thicknesses, I don't see a problem with leaving the structure as welded.

I've scowered the web and read quite a bit on this topic. But I still have questions that I want to run past you guys. It seems that a properly triangulated structure made of 4130 tube could sometimes benefit from a post-weld heating of the weldment to stress relieve and to reduce brittleness of the HAZ. I read several sources that stated to use a neutral flame of an oxy-acetylene torch to , buy cs api 5l gr b
