17-4PH Stainless Steel Powder for 3D Printing PTA & Laser Cladding

Product Overview

Our 17-4PH Stainless Steel Powder is a high-performance precipitation-hardening martensitic stainless steel specifically engineered for additive manufacturing (3D printing), plasma transferred arc (PTA) welding, and laser cladding applications. Produced via argon gas atomization, this powder delivers exceptional sphericity, low porosity, and superior mechanical properties after heat treatment.

With its unique combination of high strength, corrosion resistance, and hardness, 17-4PH is widely used across aerospace, oil & gas, marine, and industrial tooling applications.

Key Features & Benefits

✔ High Sphericity (>95%) – Excellent flowability for consistent layer deposition
✔ Precise Particle Size Distribution – Optimized for different AM processes
✔ Outstanding Mechanical Properties – Tensile strength up to 1,300 MPa after aging
✔ Corrosion Resistant – Performs well in mildly corrosive environments
✔ Heat Treatable – Can be solution treated and aged for enhanced properties
✔ Low Oxygen Content (<500 ppm) – Minimizes oxide inclusions

Available Particle Size Ranges

• 15-45μm – Ideal for high-resolution SLM/DMLS 3D printing
