The AISI 5120 is a low alloy steel, one of its main features are its extraordinary properties of strength and ductility. It is mainly represented chemically by carbon, manganese, chromium, and, in some instances, molybdenum that are known to add to its distinctive mechanical features. A picking out carbon amount of 0.17% makes it quite easy to weld and machine. Manganese presence increases hardness but chromium and molybdenum help in anti corrosive properties and high strength at high temperatures. The AISI 5120 steel is used in different areas such as automotive, aircraft, and machined components manufacturing. It is capable of meeting the needs of components that carry loads subject to high stresses and wear, such as rollers, bearings, and screws. Extensive charts and online PDFs give comprehensive data on its structure, mechanical properties, and applications that engineer and metallurgists can use to select applicable materials for design processes.
AISI 5120 steel, another name for SAE 5120, for industrial applications as it has a diverse range of characteristics making it suitable for numerous industrial applications. Its chemical consistence usually contains carbon, manganese, silicon and sulfur, chromium and molybdenum in different percentages which leads to its high strength, toughness and ability to resist wearing. Widely employed in alloys of gears, shafts and other machine components, AISI 5120 is characterized by great welding ability and workability when empowered by heat treatment. This steel comes under the AISI/SAE steel designation system and it is graded within the 51xx series, which is notorious for their superior performance in dramatically rigorous surroundings.

Advantages:
High hardenability: Chemical composition has high hardenability and can reach forged specific hardnesses during heat treatment.
Good strength: Offers satisfactory elastic and tensile strength, which makes it appropriate for many engineering purposes.
Wear resistance: Furnishes desirable measures of wear protection which leads to increase durability of components in usage to abrasion.
Machinability: Especially easy to turn as well as bore and practice and ream giving a smooth manufacturing procedure and short time for manufacturing.
Disadvantages:
Susceptible to corrosion: Can be vulnerable to corrosion in particular harsh conditions, thus being in need of protective coatings.
Limited availability: As with any innovative material, AISI 5120 alloy steel may not be easily obtainable due to its market demand and production timelines.
Cost: On certain occasions, AISI 5120 alloy steel can be more expensive when compared against some of the materials that it competes against.
Weldability: May also have certain issues of welding with materials that may need proper assessment before welding and proper techniques of welding to be used.
