Bohler Fox CN 22/9 N-B (Duplex) Stainless Steel Stick Electrodes
Basic coated, core wire alloyed electrode of E 22 9 3 N L B / E2209-15 type for welding of duplex stainless steels such as 1.4462 / UNS S31803 and S32205. Specially designed for the joining of thick-walled sections (e.g. > 20 mm) and rigid constructions as well as for applications where extra low service temperature requirements exist (down to -50ºC). The weld metal meets the corrosion test requirements per ASTM G48 Methods A, B and E (25ºC) and shows high resistance to stress corrosion cracking. The electrode provides user-friendly operating characteristics in all positions except vertical down with good slag removability and weld bead appearance. Additionally the fi ller metals offer high safety against formation of porosity. Ferrite measured with FeritScope FMP30 34 – 36 FN. Suitable for service temperatures from –50ºC to 250ºC.
