INTRODUCING 15-5 PH STAINLESS STEEL: A HIGH-STRENGTH, CORROSION-RESISTANT ALTERNATIVE
Advanced Precipitation-Hardened Steel for Critical Industrial Applications
15-5 PH stainless steel (UNS S15500) is a martensitic precipitation hardening grade that combines high strength and toughness with excellent corrosion resistance. Traditional manufacturing of 15-5 PH components often involves long lead times and geometry constraints that limit design possibilities.
Metal 3D printing changes this. With laser powder bed fusion, complex 15-5 PH parts can be produced with design freedom that machining or casting cannot match—while maintaining the mechanical properties this material is known for.
Typical Applications of 15-5 PH Stainless Steel
15-5 PH stainless steel is widely used in demanding industries due to its excellent combination of strength, toughness, and corrosion resistance. Typical applications include structural parts in the aerospace sector, such as airframe fittings and landing gear components, where high strength-to-weight ratio and durability are critical. In the healthcare sector, 15-5 PH is employed for manufacturing medical devices and precision instrumentation parts that require both mechanical reliability and corrosion resistance.
Additional applications include:
- Valves and fluid control components, offering excellent wear resistance and performance in corrosive environments
- Oil and gas industry components, such as offshore hardware and subsea equipment exposed to harsh conditions
- High-strength fasteners and fittings used in various industrial sectors
- Precision mechanical parts requiring dimensional stability and corrosion resistance
- Pump shafts, impellers, and wear rings in marine and industrial environments
Why Choose 15-5 PH Stainless Steel for 3D Printing?
- Exceptional strength-to-weight ratio – With yield strength up to 1275 MPa and tensile strength reaching 1380 MPa after heat treatment, 15-5 PH is used in aerospace and other high-performance applications where strength matters.
- Superior transverse properties compared to 17-4 PH – Lower delta ferrite content means better toughness and dimensional stability, especially in larger cross-sections.
- Excellent corrosion resistance – This grade performs well in marine, petrochemical, and industrial environments, outperforming grades like 410 and 431 stainless steels.
How Our 15-5 PH Metal Printing Process Works
Design optimization – We review your geometry and provide DfAM (Design for Additive Manufacturing) consultation to ensure your 15-5 PH parts are optimized for printing if needed!
Precision printing – Components are built using laser powder bed fusion with certified and tested 15-5 PH powder under controlled conditions.
Post-processing and verification – Parts undergo heat treatment, machining if required (subcontracted if complex), and quality inspection to meet your specifications.
