A-Powder by AO Metal · 316L
A-Powder 316L is the low-carbon, molybdenum-bearing stainless steel in AO Metal’s powder line — a forgiving first alloy for a new LPBF machine and a dependable choice for parts that see water, chemicals or salt.
316L powder in brief
- Molybdenum for corrosion resistance — better pitting and chloride resistance than 304-type stainless.
- Ductile and weldable — no ageing step after printing; stress-relieve and finish.
- Easy to qualify — a common first alloy when a team brings up a new LPBF system.
About A-Powder. A-Powder is AO Metal’s own line of LPBF metal powders, produced in China under an ISO 9001 quality system. Additive Plus sells and supports it in the US — you order and pay here, and our materials engineer answers your questions.

Complete the workflow
- ✓ 316L — stronger pitting and chemical resistance than 304 stainless
- ✓ Precision-ground flatness for consistent first-layer adhesion
- ✓ Made to order — choose your speed below: Express 2–3 wks, or Standard 6–8 wks (save ~45%)
Immersion-separation industrial vacuum for reactive metal powder — aluminium, titanium and similar alloys — in 3D printing and powder handling. Captures powder under liquid so it's never a dry, ignition-sensitive cloud. ATEX-rated, antistatic, single-phase.
- ✓ For reactive AM powder (Al, Ti, Mg) — the safe alternative to a dry vacuum
- ✓ Two-stage antistatic filtration + grounded construction · ATEX docs on request
- ✓ In US stock · ships in 2 business days · genuine Delfin unit
Hose and tools are not part of the standard configuration. The Delfin KT1006 accessory kit ($721) fits this 2-inch inlet: 10 ft hose, wand, floor brush and nozzle.
Automated 2-in-1 blasting cell that depowders and surface-finishes powder-bed 3D-printed parts in one enclosed, software-controlled cycle.
- ✓ Depowdering + surface finishing in one ATEX-compliant cell
- ✓ Polymer PBF (SLS, MJF, HSS, SAF) + de-powdered metal parts
- ✓ Lead time: 6–9 weeks — built to order · install + training included
