Exaton 16.5.1
16.5.1 is a filler material for joining EN 1.4418 and similar steels. It is also used for overlay welding. The weld metal has excellent resistance to cavitation and is used typically for shafts, propellers, pumps and valves in for example, hydropower generation.

CORROSION RESISTANCE: The weld deposit is resistant to scaling in air up to 850 °C (1560 °F).
Its pitting and general corrosion resistance is comparable to EN 1.4306, ASTM 304.
RECOMMENDED WELDING DATA:
The parameters for TIG welding depend largely upon the base metal thickness and the welding application.
Electrode negative and a shielding gas of argon or helium should be used to prevent oxidation of the weld metal.
WELD METAL CHARACTERISTICS: Martensitic/austenitic microstructure with a ferrite content of 12 FN.
