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
