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

It has the highest strength compared to the other variants of SAE-AISI 4130 steel. The graph bars on the material properties cards below compare quenched and tempered SAE-AISI 4130 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.
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.
Tempering temperature of 4130 alloy steel can be from 204-649 C (400-1200F) after normalizing and water quenching, and the corresponding Rockwell hardness can be obtained. Forging. Material 4130 alloy steel forging temperature is about 1204 C (2200 F) Welding 4130 Steel

Both normalized SAE-AISI 4130 and quenched and tempered SAE-AISI 4130 are variants of the same material. They share alloy composition and many physical properties, but develop different mechanical properties as a result of different processing.

Polymer Quenching. Forgings. Forging Heat Treatment with Polymer Quenching Polymer quenching provides a hardening heat treatment for steel forgings. Polymer quenching can be utilized with excellent results on plain carbon and alloy steels that require superior depth of hardness and uniform, repeatable mechanical properties.

AISI 4130 steel Annealing delivery 4130 With a lower carbon content range, So the 4130 alloy steel have better weldability than AISI 4140 Alloy steel.
AISI 4130 steel stockholders and suppliers, delivering to the whole of the UK. AISI 4130 is a chromium molybdenum alloy steel specification. It is supplied as round bar commonly in the hardened and tempered condition with a hardness of 18-22 HRc.
to some extent due to residual alloy content, agitation of the quenching medium and other variable factors. Therefore, the tables and charts on the following pages are offered only as a guide to (1) those properties that may normally be expected from a particular grade of steel and (2) the treatment to use in order to obtain the desired properties.
TimkenSteels 4130HW steel is a fine-grained, low-alloy steel that offers optimum heat-treat response in heavier . cross-sections. It is used in a variety of bar and tubing applications in quenched/tempered conditions. Yield strengths range from 80 ksi through 95 ksi but may be tempered to higher strength levels.
4130 chromoly only has 30 points of carbon so it's not going to harden appreciably no matter what you do. 4130 is used in airframes because it doesn't bend easily or work harden. You don't want your Piper's wings to work harden while they flex and light plane wings flex, heck they flap sometimes. 4130 is most commonly used in aircraft frames.
Tempering of AISI 4130 steel can be performed at 399 to 566C (750 to 1050F), depending on the desired strength level. Hardening of AISI 4130 steel can be done with cold working or heat treatment. Some of the major applications of AISI 4130 alloy steel are in aircraft engine mounts and welded tubing.
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 the steel. 4130 steel hardening treatment creates martensite in the alloy post-quenching. The steel is normally austenitised to transform all micro constituents to 4130 steel quenching
The following is a comparison of 4130 grade steel and 4140 grade steel. This information may be useful for machining purposes and as a resource for purchasing 4130 and 4140 steel. Chemical Properties The chemical properties of 4130 and 4140 steel are similar aside from differences in Carbon and Manganese concentrations.
Integrated 4130 Chromoly head tube. So, why do we use 4130 chromoly versus other forms? Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ration and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that BMX brings without breaking (easily).
Moreover, it appears that, at least in Europe, 'quenching and tempering separately do not seem to have become common until the 15th century'; it is therefore helpful to distinguish between 'full quenching' of steel, where the quenching is so rapid that only martensite forms, and 'slack quenching', where the quenching is slower or interrupted 4130 steel quenching
Hardened and Hardenable Metals Suitable for Making Armour. Last Changed: Nov. 05, 2017. General Notes. Notes on the Ductility Needed for Armour One rule of thumb that I've developed is for how ductile the steel used for full contact armoured combat sport armour should be.
Steel is a common durable alloy, and while most steel used in tools is already tough, you can harden it even more to prevent wear and tear. Hardened steel prevents knife blades from dulling and tools from bending and breaking.
Once the piece is hot enough, which can be seen as a bright, yellow glow of the steel, you want to quickly and carefully grab the part and place it quickly into the oil or water. Stand back as hot fluids will be ejected. The choice of water will provide hardness. Oil will add carbon to the steel, making it harder, but also a little brittle.
