SPECIFICATION:
AWS 5.9 Class ER209 / ASME SFA 5.9 Class ER209
CLASSIFICATION:
ER209 / UNS S20980
DESCRIPTION / APPLICATION:
- ER209 is most often used to weld Nitronic® 30, and Nitronic® 50 base metals.
- This filler metal can also be used in welding dissimilar alloys like mild steel and the stainless steels, and also for direct overlay on mild steel for corrosion applications when used with the gas metal arc welding process.
- ER209 is a nitrogen strengthened, austenitic stainless steel exhibiting high strength and good toughness over a wide range of temperatures.
- Weldments in the as-welded condition made by using this filler metal are not subject to carbide precipitation.
- Nitrogen alloying reduces the tendency for carbon diffusion and thereby increases resistance to intergranular corrosion.
