SIDER 2209 (E2209L-16 Calcium-Rutile Welding Elettrode)
SIDER 2209 is an all position welding electrode designed to run on direct current, reversed polarity as well as alternating current.This electrode is used for welding ferritic-austenitic (duplex) steels, especially those with high resistance to stress corrosion cracking.
Sider 2209L-16 is also used for welding on stainless structures where a particularly high strength is required.
This electrode deposits weld metal of ferritic-austenitic chromium-nickel-molybdenum steel with low carbon content for service temperature up to 280°C.
Supplied in diameters: 2.0 - 2.5 - 3.25 - 4.0 mm.
