Sandvik 19.9.NbR-16 (347-16) is a niobium-stabilized chromium-nickel covered electrode with rutile-acid coating for welding of steels of ASTM 321 and 347 types as well as overlays. It is used in structural applications at max 400°C (752°F). The coating for this electrode is of the American rutile type with a faster freezing rate over -17 type of the same weld deposit chemistry.

The electrode has excellent arc stability and fast burn off rate with minimal stub loss. It is also characterized by improved moisture resistance, self peeling slag, high resistance to porosity and easy post weld finishing. Sandvik 19.9.NbR-16 (347-16) gives smooth uniform beads and works in any standard weld position.
