Globus Metal Powders

GMP® 15-5PH™

GMP® 15-5PH™

Precipitation-Hardening Stainless Steel Powder for High Strength and Corrosion Resistance

GMP® 15-5PH™ from Globus Metal Powders is a martensitic precipitation-hardening stainless steel powder engineered for excellent mechanical strength, toughness, and corrosion resistance, with enhanced manufacturability for PM-HIP and additive manufacturing processes. Produced via argon inert gas atomisation, this powder features ultra-low oxygen content, tightly controlled minor elements, and optimised spherical particle morphology, making it ideal for PM-HIP, additive manufacturing (AM), and metal injection moulding (MIM). 

15-5PH™ is widely utilised in aerospace, defence, petrochemical, marine and medical applications, where components require high-strength performance, corrosion resistance, and reliability under cyclical loads. Its precipitation-hardening capability allows precise tuning of mechanical properties through ageing treatments, making it suitable for mission-critical components with strict dimensional and mechanical tolerances. 

Differentiation

Across the Globus portfolio: 

  • Versus 17-4PH: Both are precipitation-hardening steels, but 15-5PH offers enhanced corrosion resistance and improved toughness, particularly in marine and chemical environments, while maintaining comparable high-strength performance. 
  • Versus nickel superalloys (718, 625, Alloy X, 939): 15-5PH is optimised for moderate temperature strength and corrosion resistance, whereas nickel superalloys target extreme high-temperature creep, fatigue, and oxidation resistance. 
  • Versus stainless steels (316L, F53): 316L prioritises general corrosion resistance and F53 provides chloride stress corrosion resistance, while 15-5PH combines high strength, toughness, and corrosion performance. 
  • Versus ferritic-martensitic steels (P91, EUROFER97): P91 and EUROFER97 are selected for high-temperature structural stability, whereas 15-5PH is suitable for medium-temperature structural and marine applications. 
  • Versus Invar 36: Invar offers low thermal expansion, while 15-5PH focuses on mechanical strength and corrosion resistance. 

 

GMP® ultra-low oxygen powders with tightly controlled minor elements reduce oxide inclusions, internal voids, and consolidation defects, ensuring reliable PM-HIP densification and defect-free additive manufacturing builds. The spherical particle morphology and optimised PSD provide predictable flow, uniform packing, and consistent layer deposition. 

Applications

  • Aerospace & Defence: structural components, landing gear, marine hardware, and high-strength fasteners. 
  • Oil & Gas: valves, pumps, and pressure-resistant components. 
  • Chemical & Marine: equipment requiring both mechanical integrity and corrosion resistance. 
  • Medical: surgical instruments and implants with biocompatibility and resistance to sterilisation process 
  • Additive Manufacturing: complex geometries with reliable mechanical performance. 
  • PM-HIP & MIM: dense, near-net-shape components with tailored mechanical properties. 

Key Advantages

  • High-strength, precipitation-hardened mechanical performance for structural applications. 
  • Enhanced corrosion resistance in marine and chemical environments. 
  • Ultra-low oxygen and tightly controlled minor elements for defect-free densification. 
  • Spherical particle morphology and optimised PSD for consistent flow, packing, and layer deposition. 
  • Internal laboratory verification ensures chemistry, PSD, and density consistency. 
  • Customisable powders tailored for PM-HIP, AM, and MIM.
