AISI 4032 Molybdenum Alloy Steel Chemical Composition & Properties, Grades, Table and Document

AISI 4032 is in the group of molybdenum steel alloys, has a high toughness, and an exceptional wear resistance. Such composition is the chemical one, which ordinarily includes carbon, manganese, silicon, phosphorus, sulfur, chromium, and mo- lybdenum. In the process of thermal coating, bridging of bonds produces a particular type of intertwining material that is desirable for numerous purposes including such as high tensile strength, wear-resistant, and toughness applications. AISI 4032 which is doped with molybdenum, chromium, and vanadium is frequently applied in high load, strength and durability; accordingly, it is suitable for the manufacture of gears and shafts in some high-efficiency industries such as automotive, aerospace and machinery. Its ratings are stancdardized, providing precision and standardization in the game. Table, chart and documenting describing its parts, properties, and classes would be essential sources providing the engineers and the manufacturers with the exact information to consider.

AISI 4032 Alloy Steel Chemical Composition And Grade Table

AAISI 4032 alloy steel is an alloy steel of low-alloy type which has shown certain superiority over others owing to high strength, toughness, and wear resistance. The chemical makeup of this material is mainly made up of carbon, manganese, silicon, chromium, nickel, molybdenum and other elements. The exact composition or the right proportion of the ingredients used for concrete fabrication may change depending on the concrete manufacturer and the concrete applications demands. Grade tables may be explained here by AISI 4032 that demonstrate the very weight of each and every element used and this will provide consistency and quality during the production process. As a valuable informational resource these charts are used by engineers, metallurgists, and manufacturers,from various industries, while they deal with non-heat/cold treated AISI 4032 alloy steel.

Advantages and Disadvantages of AISI 4032 Molybdenum Alloy Steel


  • Heat Treatable: Holds a high degree of workability and can be heat treated to required mechanical specifications.

  • Dimensional Stability: Minimal warping after heat treatment.

  • Wear Resistance: Durable enough to resist wear, especially in tough working conditions.

  • Strength: Excellent tensile properties suitable for structures.


  • Cost: Higher cost than low alloy steel regarding their limits of use.

  • Weldability: Welding can be very difficult and requires unique techniques.

  • Corrosion Resistance: Requires proper protection due to relatively low corrosion resistance.

  • Machinability: Tensile strength falls when hardness rises, negatively affecting machinability.
