Описание и область применения
Basic electrode, core wire alloyed, for welding of ferritic-austenitic duplex materials, e.g. 1.4462, UNS S31803. Besides the high tensile strength, the special advantage of the weld metal of this electrode is its very good toughness behaviour down to –60°C. Furthermore the high crack resistance of the weld metal and the particularly good resistance to stress corrosion cracking and pitting behaviour are significant features. FOX CN 22/9 N-B is 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. The Pitting Resistance Equivalent (PREN) shows values of 35 in accordance with the formula (%Cr + 3.3% Mo + 16% N). The pitting resistance according to ASTM G48 / method A shows good results. The electrode provides user friendly operating characteristics in all positions except vertical down with good slag removability and weld bead appearance. Additionally the filler metals offer high safety against the formation of porosity.
