SIDER NF 55 GMAW wire for cast iron

SIDER NF 55 is used for the welding of gray, ductile, malleable, and Ni-Resist cast iron. This filler metal is extensively employed to overlay cast iron rolls. It is also used to repair castings. This wire is also used for welding cast irons to various wrought materials, including carbon steels, low-alloy steels, and nickel alloys. SIDER NF 55 is especially useful for welding heavy sections and high-phosphorus irons. The weld metal of SIDER NF 55 is harder than that of Alloy 99 (AWS ERNiCl). However, the machining can be accomplished by using carbide tipped tools. A preheat and interpass temperature of 175°C (350°F) minimum is recommended during welding, without which the weld and heat affected zones could develop cracks. Available in diam.: 1.2 mm; on spools of 15 kgs:
