AISI 4130 Modified (AISI 4130M) is an alloy steel that is readily machinable and supplied in the annealed or normalized condition. It is a low carbon and chromium containing alloy with additions of molybdenum to provide excellent fatigue strength and toughness. It is easily heat treated and welded to a wide variety of applications. The chemistry and mechanical properties of AISI 4130M make it an ideal grade for applications such as structural components and shafts, linkage components and ball screws, screw and nut assemblies, cold headed parts, and small tools.
AISI 4130M is an improved version of AISI 4130 (also known as SAE 4130). AISI 4130M is a modified material that provides higher strength levels compared to the regular 4130 grade. This material is superior in terms of its fatigue and hardness properties compared to the 4130 grade and boasts a higher level of machinability. The alloy can be heat treated in order to strengthen its mechanical properties.
AISI 4130M is a low alloy steel containing 1% chromium and 0.2% - 0.3% molybdenum as strengthening agents. The material has good weldability and high strength properties, which makes it ideal for parts that require strength and corrosion resistance. Properties such as toughness, hardness, strength and fabrication proceedures, make AISI 4130M a good choice for many machined parts.
For highly demading applications such as aerospace applications, AISI 4130M is often combined with other high strength alloys such as SAE 4340 and SAE 4150. This combination results in a higher performing alloy with superior strength and fatigue properties.
The properties of AISI 4130M make it an ideal grade for use in many different applications. It is well suited for applications such as mechanical components, heavy machinery, oil and gas equipment, agricultural equipment and automotive components. This material is easily machined and welded, making it highly versatile.
AISI 4130M is commonly supplied in the annealed or normalized condition, as well as the “M” designation which indicates that the material has been modified to increase its strength. This modified material is often utilized in extreme cold and hot temperature environments.
In subsequent heat treatments, AISI 4130M acquires additional strength and ductility due to its greater amount of molybdenum content. As a result of its machinability and weldability, this alloy is a suitable choice for many applications where high strength and durability are requuired.
AISI 4130M is an ideal material for parts such as flanges, tubing, and pipe fittings as it does not require as much energy to machine as some other materials. Due to its good fatigue properties, it is often used to create parts that are subject to high vibration or cyclic loading. It is also a good choice for cold heading applications such as fasteners, pins, and screws as it is strong and resistant to wear and tear.
AISI 4130M is an excellent choice for applications that require high strength and durability. Its combination of good machinability and weldability further adds to its usefulness for applications in many different industries. In summary, AISI 4130M is a modified steel that is excellent for many applications and industries.
