Description: Our 304L stainless steel powder 10Ni grade is a premium austenitic powder designed for critical net shape manufacturing processes including Metal Injection Molding (MIM), binder jetting additive manufacturing, and precision powder metallurgy. With a precisely controlled nickel content of 10.0% and extra low carbon (≤0.03%), this grade offers significantly enhanced austenite phase stability, improved pitting corrosion resistance, and exceptional sintered ductility. The optimized particle size distribution (D10=3.0μm, D50=8.5μm, D90=20.0μm) ensures high packing density, excellent flowability, and consistent green strength (>5.35 g/cm³). After sintering at approximately 1375°C, the material achieves a sintered density of ≥7.78 g/cm³, shrinkage ratio of 1.165, and debinding rate of ~7.4%. Mechanical properties include tensile strength ≥250 MPa, yield strength ≥180 MPa, elongation ≥50%, and hardness >130 HV, meeting the most demanding specifications for corrosion resistant and high integrity stainless steel components.

Categorized Applications & Advantages
1. Metal Injection Molding (MIM)
Elevated 10% nickel content significantly improves austenite stability, enabling production of thin walled components with excellent toughness and impact resistance
Extra low carbon (≤0.03%) eliminates chromium carbide precipitation during sintering, ensuring superior intergranular corrosion resistance for complex geometries
Stable shrinkage ratio (1.165) and consistent debinding behavior support high volume production of precision parts such as medical instrument handles, dental tools, and electronic device structures
2. Additive Manufacturing – Binder Jetting & Powder Bed Fusion
Narrow particle size distribution with D50=8.5μm delivers high apparent density and smooth powder recoating for defect free green parts
10Ni grade allows post sintering welding, laser re melting, or surface treatment without sensitization, ideal for additively manufactured manifolds and custom implants
3. Corrosion Resistant Components for Harsh Environments
10% nickel combined with 18% chromium provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride rich environments including marine hardware, offshore platform components, and chemical processing valves
Outperforms standard 304 and 304L 8Ni grades in acidic and saline media, extending service life of critical parts
4. High Ductility Mechanical Parts Requiring Cold Forming
Elongation ≥50% allows post sintering operations such as crimping, bending, flaring, or thread rolling without fracture
Maintains tensile strength ≥250 MPa for structural applications including pneumatic fittings, fuel system connectors, and spring housing components
Advantages Overview
Enhanced Corrosion Resistance: 10Ni grade offers superior pitting resistance equivalent to 316 in mild chloride environments while retaining 304L cost effective processing characteristics
Phase Stability: Higher nickel content prevents martensite formation during cold deformation, ensuring non magnetic properties and stable performance across wide temperature ranges
Process Reliability: Consistent melt flow index (4386 g/10min) and debinding rate (7.4%) minimize process variation in automated MIM and binder jetting lines
Post Sintering Freedom: Parts can be welded, brazed, or heat treated without risk of intergranular corrosion or ductility loss
Wide Industry Compliance: Meets ASTM F899 for surgical instruments, ISO 5832 1 for implantable devices, and NACE MR0175 for sour service applications when properly processed
