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.
Across the Globus portfolio:
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.
Whether you require ultra-low oxygen grades, bespoke particle size distributions or high-volume supply, our team is ready to support your requirements.
