Description
17-4PH Stainless Steel Alloy Powder is a premium, gas-atomized martensitic precipitation/age-hardening alloy engineered for LPBF additive manufacturing. Its spherical particle morphology, controlled particle size (15–53 µm), and low oxygen content ensure stable recoating, minimal spatter, and reproducible layer fusion, enabling high-quality builds across production batches. Heat treatment allows optimization of mechanical properties, achieving ultimate tensile strength of 1300 MPa, yield strength of 1100 MPa, elongation of 10 %, and hardness of 43 HRC. OEM-optimized by A-Powder and manufactured by AO Metal, this powder combines predictable LPBF performance with consistent small-batch quality, fast delivery, and full traceable documentation, enabling engineers to produce durable, functional, and precise end-use components efficiently
