QuLPA-Fe44 Powder – Laser Cladding Powder Stainless 1.4404 / 316L (ER316L) – Austenitic, Corrosion Resistant
QuLPA-Fe44 Powder – Laser Cladding Powder Stainless 1.4404 / 316L (ER316L) – Austenitic, Corrosion Resistant
QuLPA-Fe44 is the stainless cladding powder of the range: ~AWS A5.9 ER316L — an austenitic CrNiMo steel (Cr 17 % · Ni 12 % · Mo 2.5 % · C 0.03 %).
It is the matching build-up material for the common austenitic stainless steels 1.4404 (316L), 1.4571 (316Ti), 1.4541 (321) and 1.4301 (304). The low carbon content (0.03 %) keeps the deposit resistant to intergranular corrosion. It is deliberately not a wear powder: at 180 HB the deposit is soft and tough — it restores geometry and corrosion resistance, not hardness.
Recommended base materials

Typical applications
- Repair and dimensional build-up on stainless components
- Chemical, food and plant engineering
- Corrosion protection layers on steel
- Area cladding by laser metal deposition (LMD)
Properties and advantages
- Low carbon (C 0.03 %) — resistant to intergranular corrosion
- Mo-alloyed (2.5 %) — pitting resistance
- 180 HB — tough deposit, not a wear layer
- Good polishing and machining. Grain size 53–150 µm
Powder form: grain size 53 - 150 µm — for laser metal deposition (LMD).
