Maraging Steel Forgings — Maraging 300 (AMS 6514) & Maraging 350 — Ultra-High Strength Aerospace Grade
Shivam Forge manufactures forgings in maraging steel (Maraging 300 per AMS 6514, and Maraging 350) — an ultra-high-strength, low-carbon nickel-cobalt-molybdenum alloy achieving exceptional strength (up to 2000+ MPa) through a simple, low-distortion age-hardening heat treatment — for aerospace landing gear, rocket motor casings, and tooling applications where maximum strength-to-weight ratio is the dominant design driver. Full solution treatment and ageing, EN 10204 3.1/3.2 certification. Rajkot, India. Call +91-9265772827.
Maraging steel occupies a distinctive position among ultra-high-strength alloys: unlike conventional high-strength steels that develop their properties through carbon-based martensitic hardening (requiring careful, often distortion-prone quenching), maraging steel is a very low-carbon nickel-cobalt-molybdenum alloy that develops its exceptional strength — commonly 1750-2400 MPa depending on grade and condition, among the highest of any commercially forgeable steel — through a simple age-hardening (maraging) heat treatment involving air cooling after solution treatment followed by a straightforward ageing cycle, without the quench-related distortion risk conventional high-strength steel heat treatment introduces. This combination of ultra-high strength and unusually good dimensional stability through heat treatment makes maraging steel the preferred material for aerospace landing gear components, rocket motor casings, and high-performance tooling applications where both maximum strength-to-weight ratio and precise final dimensional control matter simultaneously.
Maraging 300 (AMS 6514) forgings for aircraft landing gear structural components, where the combination of ultra-high strength (allowing reduced component weight for a given load capacity) and good fracture toughness suits the demanding, safety-critical loading landing gear experiences.
Maraging steel forgings for solid rocket motor casing applications, where maximum strength-to-weight ratio directly improves rocket performance, and maraging steel's low-distortion heat treatment supports the dimensional precision thin-walled, high-pressure motor casings require.
Maraging steel forgings for high-performance die and tooling applications requiring exceptional strength and wear resistance combined with the dimensional stability maraging steel's low-distortion heat treatment provides — critical for precision tooling where post-heat-treatment dimensional shift would compromise tool accuracy.
Maraging steel forgings for motorsport and other high-performance applications where component weight reduction at maximum strength justifies the material's premium cost, similar to the material selection logic applied across our broader motorsport forging product line.
Full solution treatment (typically 815-825°C, air cool) followed by precise age-hardening (maraging) heat treatment (typically 480-510°C) developing the alloy's characteristic ultra-high strength through intermetallic precipitation rather than carbon-based martensitic transformation.
Maraging 300 forgings supplied to AMS 6514 chemistry and mechanical property requirements where aerospace programme specification demands, with full heat treatment and testing documentation.
Dimensional verification confirming the low-distortion characteristics maraging steel's air-cool heat treatment mechanism provides, an important consideration for precision components where post-heat-treatment machining allowance planning depends on predictable dimensional behaviour.
Material test certificates per EN 10204 3.1 as standard, with 3.2 third-party witnessed certification available for aerospace and other regulated application documentation requirements.
Maraging steel's engineering significance comes from resolving a practical manufacturing challenge that limits how effectively conventional ultra-high-strength steels can be used for precision components: developing genuinely high strength in conventional alloy steel requires martensitic transformation through rapid quenching, a process that inherently introduces dimensional distortion risk, particularly in complex or thin-walled geometries where uneven cooling rates across the part can cause meaningful shape change. Maraging steel sidesteps this problem entirely through a fundamentally different strengthening mechanism — very low carbon content combined with nickel, cobalt, and molybdenum alloying develops strength through intermetallic compound precipitation during a relatively gentle age-hardening treatment, requiring only air cooling from solution temperature rather than the aggressive quench conventional high-strength steel hardening demands.
This low-distortion characteristic matters enormously for the applications where maraging steel sees its heaviest use: aerospace landing gear components and rocket motor casings both demand extremely precise final dimensions (landing gear for reliable mechanical function under severe, safety-critical loading; motor casings for consistent wall thickness supporting predictable pressure containment), and maraging steel's ability to achieve ultra-high strength without the dimensional unpredictability quench-hardening introduces makes it possible to forge and heat-treat components closer to final dimension, reducing the machining stock allowance and associated cost that more distortion-prone conventional high-strength steel would require.
The strength levels maraging steel achieves — commonly 1750-2400 MPa depending on grade and ageing condition — place it among the highest-strength commercially forgeable steel materials available, a strength-to-weight advantage that translates directly into component weight reduction for any application where structural capacity, rather than stiffness or other material properties, is the limiting design constraint. This makes maraging steel's premium material cost (reflecting its nickel-cobalt-molybdenum alloy content) a worthwhile trade-off specifically in weight-critical applications like aerospace and motorsport, where the value of weight saved often exceeds the material cost premium paid to achieve it.

Maraging steel is a very low-carbon nickel-cobalt-molybdenum alloy that develops ultra-high strength through a simple age-hardening (maraging) heat treatment involving air cooling and ageing, rather than the carbon-based martensitic quench hardening conventional high-strength steel requires. This gives maraging steel unusually good dimensional stability through heat treatment alongside its exceptional strength.
Maraging steel commonly achieves 1750-2400 MPa tensile strength depending on the specific grade and ageing condition, among the highest strength levels of any commercially forgeable steel — substantially exceeding what conventional alloy steels or even most other high-strength stainless grades can deliver.
