Maraging Steel

Strength, Hardness, Ductility

Maraging Steel is a high-strength alloy known for its exceptional mechanical properties and excellent resistance to corrosion. It is typically produced through a process called precipitation hardening, which involves aging the material to achieve its desired strength.

The name "maraging" is derived from the combination of "martensite" and "aging." The alloy initially undergoes a solution treatment to form a supersaturated solid solution, followed by a rapid cooling process to transform the structure into martensite. Subsequently, the material is subjected to a low-temperature aging process, which leads to the precipitation of intermetallic compounds. This aging process enhances the strength and hardness of the material while maintaining its ductility.


  • Aerospace:

    Maraging Steel is widely utilized in aerospace applications due to its high strength, excellent mechanical properties, and good corrosion resistance. It is used in the manufacturing of aircraft components, rocket engines, landing gear parts, and structural components.

  • Tooling and Molds:

    Maraging Steel is favored in tooling and mold making industries due to its high hardness, wear resistance, and dimensional stability. It is used to create molds, dies, and tooling inserts for injection molding, blow molding, and extrusion processes.

  • Automotive:

    Maraging Steel finds applications in the automotive industry, particularly in areas that require high strength and durability. It is used in the production of engine components, transmission parts, suspension components, and safety system components.

  • Defense and Military:
