Our 304 stainless steel powder (8Ni grade) is engineered for demanding powder metallurgy applications, particularly Metal Injection Molding (MIM). With precisely controlled chemistry (Cr 18.19%, Ni 8.06%) and a balanced particle size distribution (D10=3.0μm, D50=8.5μm, D90=20.0μm), this powder ensures consistent flowability, high green density (>5.35 g/cm³), and exceptional sintered performance. After sintering at ~1375°C, it achieves a density of ≥7.78 g/cm³, shrinkage ratio of 1.165, and binder burnout rate of 7.4%. The resulting parts deliver robust tensile strength (≥250 MPa), yield strength (≥180 MPa), elongation (≥50%), and hardness (>130 HV), making it ideal for high-reliability industrial components.

Key Applications & Advantages
1. Metal Injection Molding (MIM)
Optimized particle size distribution ensures high packing density and defect-free green parts.
Low impurity levels (C≤0.05%, O≤0.385%) reduce sintering defects and improve final part consistency.
Shrinkage ratio of 1.165 enables precise dimensional control for complex geometries.
2. Additive Manufacturing (Binder Jetting / DED)
Excellent flow characteristics (MFI 4386 g/10min at 190°C/21.6kg) support smooth layer spreading and powder recoating.
High sintered density and elongation (>50%) allow for post-processing like heat treatment or surface finishing.
3. Powder Metallurgy & Press-and-Sinter
Achieves >7.78 g/cm³ sintered density, close to wrought 304 properties.
Superior corrosion resistance from balanced Cr/Ni content (18.19% Cr, 8.06% Ni).
Advantages Overview
Consistent Mechanical Performance: Guaranteed tensile strength ≥250 MPa and yield ≥180 MPa meet ISO/ASTM standards for 304 stainless steel.
Process Stability: Stable debinding rate (7.4%) and narrow sintering window reduce scrap rates in mass production.
Fine Microstructure Control: D50=8.5μm with moderate fines (D10=3.0μm) enhances sintering activity while maintaining good handling properties.
Versatile Part Geometry: Supports thin walls, undercuts, and internal channels without secondary machining.
