Stainless steel powder grades
Water-atomized 316L and 304L stainless steel powder, 150 to 250 mesh, factory direct from RS&M (Rongsheng).
316L Stainless Steel Powder
316L Stainless Steel Powder · 150 mesh (≈100 µm)
Water-atomized 316L stainless steel powder, sieved at 150 mesh (≈100 µm cut point). Specified for sintered filter cartridge support layers, medium-precision single-layer filters, and press-and-sinter PM components. Batch-level CoA.
- Particle size:
- 150 mesh (≈100 µm cut point; typical D50 ≈ 75–90 µm)
- Morphology:
- Irregular, sub-spherical (water-atomized cauliflower morphology)
- Chemistry:
- 316L UNS S31603 (C ≤ 0.030 / Cr 16–18 / Ni 10–14 / Mo 2–3 / Mn ≤ 2 / Si ≤ 1)
316L Stainless Steel Powder · 200 mesh (≈75 µm)
Water-atomized 316L stainless steel powder, sieved at 200 mesh (≈75 µm cut point). The transition size between coarse support and fine filtration layers in multi-layer sintered cartridges; also a core grade for medium-precision single-layer cartridges.
- Particle size:
- 200 mesh (≈75 µm cut point; typical D50 ≈ 55–65 µm)
- Morphology:
- Irregular, sub-spherical (water-atomized cauliflower)
- Chemistry:
- 316L UNS S31603
316L Stainless Steel Powder · 250 mesh (≈58 µm)
Water-atomized 316L stainless steel powder, sieved at 250 mesh (≈58 µm cut point). The fine filtration layer of precision sintered cartridges and the low-roughness substrate for PTFE membrane lamination.
- Particle size:
- 250 mesh (≈58 µm cut point; typical D50 ≈ 40–48 µm)
- Morphology:
- Irregular, sub-spherical (water-atomized)
- Chemistry:
- 316L UNS S31603
304L Stainless Steel Powder
