AWS A 5.4: E 2209-17

EN 1600: E 22 9 3 N L R 32

For welding ferritic-austenitic steels. It is characterised by increased strength and toughness. The weld metal is highly resistant to corrosion cracking due to its high ferrite content. Good resistance to pitting corrosion and chlorine-containing media. Operating temperature up to + 250 °C.
