Alloy Steel 4330 MOD Distributor and Supplier

The alloy steel which is known as 4330 is considered a strong blend of various elements like iron, nickel, manganese, and silicon amongst other elements. Affiliated with the UNS designation of J24045, it is only a single example of alloy steels in a large family of them. These alloyed steels all were developed to serve various purposes based on their best strengths. It is preferred for designing many large components of aircrafts as well as for using in small parts of the engines and power transmission applications. 4330 itself has various characteristics which include high positive response to mechanical as well as heat treatments. Those properties brought together are what make 4330 a product valued greatly for a number of engineering - and especially aerospace - applications. This steel alloy in particular performs well in small components found within the engine or related to the axles and gear shafts of vehicles.

These alloy is one of a family of alloys that did not take off immediately, even when developed relatively early. Although Julius Baur, who was an American metallurgist, first patented chromium steels in 1865, they were not yet very popular. The Chrome Steel Co. attempted to produce some of this product out of Brooklyn, New York. It took chromium alloy having further development by Henri-Ami Brustlein, who was a French metallurgist, before its popularity increased in the subsequent years. As time passed, the popularity only grew. There would be more and more developments and inventions as well as societal shifts that increased the demand for various sophisticated and specifically designed metals such as this one. Eventually, the world would see many cars on the road and planes in the air amongst other changes. Unlike when the patent was first developed, today shows a time where these metals are in high demand - especially for the aerospace industry. Out of these highly demanded metals comes this particular alloy as well. Today, this alloy steel 4340 is available in different specifications, each having been created by a variety of industries that use such alloys commonly. For this alloy, specifications are typically codified under AMS 6411, AMS 6427, GM 1010, MIL-S-8699, and BMS 7-27, as well as others. The industry has not only expanded greatly to produce more of these great alloys for all the fields requiring them, but now we are also faced with regulating bodies that govern the particular features of each product to ensure the highest quality and standard of safety in what is being produced.

Chemistry of Alloy Steel 4330 MOD

The chemistry of this alloy consists of Iron (Fe), Nickel (Ni), Manganese (Mn), Silicon (Si), Chromium (Cr Molybdenum (Mo), and Carbon (C). There are also specifications to percentage by weight of these elements such as Iron (95 to 98%), Nickel (1 to 2%), Manganese (less than 1%), Silicon (less than 1%). Chromium (less than 1%), Molybdenum (less than 1%). Carbon (less than 1%). 4330 has a density of 0.28 lb/in3) with a specific gravity of 7.8. It has a Brinell classified hardness of 285, a less than 15.0% elongation at break (in 50 mm), a shear modulus of 80 GPa (or 11600 ksi), and an elastic modulus of 190 to 210 GPa (or 27557 to 30458 ksi). This alloy also has a yield strength of less than 690 MPa (or less than 100000 psi) and an ultimate tensile strength of less than 860 MPa (or less than 125000 psi).
The specifications for this alloy include AMS 6411, AMS 6427, GM 1010, MIL-S-8699, and BMS 7-27. This grade of the alloy has good characteristics for cold working, even for conventional methods. These conventional methods are also favorable for welding the material. If it is preheated and post heated per the procedure for welding, it will work well, and it can also be joined using a brazing process. Forging occurs best between the temperatures of 1204 to 982 degrees C (or 2200 to 1800 degrees F), and the steel has good formability. Its bend radii is recommended to be no sharper than a 3t. In terms of machinability, this alloy has good features in the annealed, normalized, and in the tempered conditions. It is difficult to machine this alloy, however, when it is in a hardened condition. Heat treatment out to occur when the steel is between 829 and 1525 degrees F and then to be quenched in oil. Another way to heat treat it to levels of 200 ksi or beyond is to first normalize it at 899 degrees C or 1650 degrees F, then add the heat treatment and the quenching to allow it to gain strength. While hot working the steel, it will be found that it is not popular and that its cold forming reactions are far superior. Hardening the material can be done by tempering and heat treating it. It is used often in landing gears and shafts in aircrafts. Like many of these alloys, it is also popular for gears and power transmission uses.
