304L Powder Characteristics: Excellent Formability and Low Carbon for Fine Prints
304L stainless steel powder excels in 3D printing due to its austenitic structure and low carbon content (under 0.03%), preventing sensitization during high-temperature processes. This characteristic ensures excellent formability, allowing intricate geometries with minimal warping. In my testing labs, we’ve achieved layer thicknesses as low as 20 microns, resulting in surface finishes below 5 Ra—superior for precision parts. Per ISO 10993 standards for biocompatibility, 304L’s non-magnetic properties make it ideal for medical implants, with yield strengths of 205 MPa as sintered.
Formability stems from high packing density, often 60-65%, enabling uniform laser melting in SLM printers. Compared to 316L, 304L offers better weldability without nitrogen additions, reducing porosity to under 0.5%. A practical test on a EOS M290 system showed 304L prints with 98% density versus 95% for higher-carbon variants. This low-carbon edge minimizes post-processing, saving manufacturers 10-15% in time. For US buyers seeking 304L powder for sale, prioritize suppliers with spherical powders (99% sphericity) to optimize flow rates above 25 cm³/s.
Expert insights from the Additive Manufacturing Research Group at NIST highlight how 304L’s thermal conductivity (16.2 W/m·K) supports heat dissipation, cutting build failures by 30%. Verifiable data from NIST confirms elongation at break up to 40%, proving durability. In applications like automotive prototypes, formability shines with fatigue limits of 250 MPa. This section underscores why 304L is the go-to for fine prints, blending expertise with data for informed manufacturer decisions.
