Description of Stainless Steel Powder
UNS S41000 Stainless Steel Powders, also known as ASTM, AISI 410 or EN1.4006 powder, is a a martensitic stainless chromium steel material designed for Metal Injection Moulding (MIM) applications. Stainless steel powder is a finely divided form of stainless steel, typically produced through processes like gas atomization, water atomization, or plasma atomization. It consists of small, spherical or irregularly shaped particles with high purity and excellent corrosion resistance, similar to bulk stainless steel.
Stainless steel powder Production Method (SS304, SS316l, SS 410l, SS430l)
Gas Atomization Stainless Steel Powder: Inert gas breaks molten steel into fine droplets, forming spherical particles (ideal for 3D printing).
Water Atomization Stainless Steel Powder: High-pressure water stream produces irregular, cheaper powders (common in PM parts).
Plasma Atomization Stainless Steel Powder: Ultra-fine, high-purity powders for advanced applications.
Main properties of Stainless steel powder
Composition:
- Primarily iron (Fe), chromium (Cr) (~10–30%), nickel (Ni) (~8–12%), and other alloying elements like molybdenum (Mo), manganese (Mn), and carbon (C).
- Common grades include 316L (low carbon, high corrosion resistance), 304L, 17-4PH (precipitation-hardening), and 430L (ferritic).
Particle Size & Shape:
- Size: Ranges from micrometers (µm) to hundreds of microns (e.g., 15–45 µm, 45–106 µm).
- Shape: Spherical powders (better flowability) for additive manufacturing (3D printing), irregular shapes for conventional powder metallurgy.
Properties:
- High corrosion resistance (due to chromium oxide passive layer).
- Good mechanical strength and ductility (depending on alloy and processing).
- Heat resistance and biocompatibility (used in medical implants).

Analysis of Compaction and Sintering of Stainless Steel Powders
Abstract: Compaction and sintering are basic processing steps employed for producing powder metallurgy (P/M) parts. Information of materials property change during the processing steps is primarily essential for design and manufacturing engineers. In this study, stainless steel powders (316L, 304L, 409L and 434L) were selected for investigation on the effect of densities on mechanical property. It was found that measurable parameters such as green density, sintered density and mechanical property showed linear relationships with one another for the 304L stainless steel powder. Equations, derived by using Least Square Method (LSM), may be employed with high confident for the 304L stainless steel powder. LSM analyses for other materials (316L, 409L and 434L) failed to get good agreement between the experimental data and the LSM results. Equations, derived by using LSM, are not recommended for the 316L, 409L and 434L stainless steel powders.
