Overview
OptiPowder SS17-4PH is a precipitation-hardening martensitic stainless steel powder designed for applications requiring high strength, good toughness, and corrosion resistance. Based on UNS S17400 (AISI 17-4 PH), the alloy delivers consistent mechanical performance and responds well to heat treatment, enabling a range of strength and hardness profiles depending on processing conditions.
All Continuum OptiPowders are tested and qualified by our in-house quality team before release, unless customer requirements call for additional third-party testing. Each lot is supported by a Continuum Certificate of Analysis (COA), providing documented quality data and traceability for the material supplied.
OptiPowder SS17-4PH is engineered for high-strength components requiring corrosion resistance and reliable mechanical performance, including:
Aerospace and defense hardware requiring strength and durability
Tooling, molds, and industrial components exposed to mechanical stress
Oil and gas components operating in moderate corrosive environments
Medical and dental tools (non-implant applications)

Additive Manufacturing Process Compatibility
OptiPowder SS17-4PH supports a range of AM and advanced manufacturing processes, including:
Laser Powder Bed Fusion (LPBF):
High-strength, near-net-shape components with complex geometries
Conventional routes:
Where controlled PSD and chemistry are required
Binder Jetting (MBJ)
Cost-effective production of tooling and industrial parts
Directed Energy Deposition (DED):
Repair and build-up of worn or high-value components
Available PSDs & Customization
OptiPowder SS17-4PH is available in multiple particle size distributions, including 15–45 µm, with custom PSDs, blended distributions, and program-based supply available on request to support specific process requirements and qualification needs.
Morphology
Powder morphology is predominantly spherical with minimal satellites, with no hollow particles, excessive agglomeration, or foreign-object defects visible at ~300× magnification.
Blending
Multiple heats may be blended into a single lot when each heat independently meets all chemical and PSD requirements.
Certification
Each shipment includes a certificate of analysis reporting chemical composition, particle size distribution, and any additional agreed-upon test results demonstrating conformance to specifications.
