EN designation: X9CrNiSiNCe21-11-2
Description and applications*
* Illustrative, not-exhaustive list
This filer wire is designed as an austenitic chromium-nickel steel alloyed with nitrogen and Rare Earth Metals (REM), which include cerium.
Cerium combined with silicon improves the oxidation resistance and erosioncorrosion resistance in oxidizing and neutral environments, whereas the nitrogen allows superior strength at high temperatures. Therefore, this filler wire shows excellent resistance to high temperatures (most suitable temperature range is 850 – 1100 °C), high creep strength, very good resistance to isothermal and, particularly, cyclic oxidation.
Not suitable for applications exposed to wet corrosion.
Prior to welding, it is recommended to carefully brush or ground black plates and previous weld beats.
