Product description
ABRAFIL 28 (Uranus S28) is a top-of-the-range stainless steel filler wire, specially designed for welding austenitic-ferritic stainless steels, especially duplex (22Cr) such as URANUS 45N, 2205 (1.4462) or equivalent.
It’s a nickel-chromium-molybdenum alloyed wire, close to AWS ER2209 designations.

Why choose ABRAFIL 28?
1. Specially designed for duplex stainless steels
It helps maintain a good ferrite/austenite balance after welding, essential to guarantee the mechanical and corrosion resistance of duplex steels.
2. Excellent corrosion resistance
-
Excellent resistance to pitting, crevice corrosion and stress cracking, even in the presence of chlorides.
-
For use in marine, industrial or chemically aggressive environments.
3. High mechanical performance
Thanks to the duplex structure (base metal and filler wire), we obtain :
-
-
Very high tensile and fatigue strength
-
Good low-temperature toughness
-
Better creep resistance than conventional austenitic stainless steels
-
