Nippon SF-3AM is a seamless, all-positional, rutile flux cored wire for welding low temperature steels in applications such as off-shore structures.
SF-3AM has acceptable charpy impact values down to -60 °C. The flux cored wire is CTOD-tested with good results.
Due to the seamless design, SF-3AM has an extremely low diffusible hydrogen content (typical 3 ml/100g) which greatly reduces the risk of hydrogen (cold) cracking.
SF-3AM has low visible welding fume and has excellent weldability in all welding positions. The wire has a clean copper coated surface which, together with exact diameter and roundness obtained with exact Japanese engineering, ensures stable and even wire feeding.
Argon/CO2 mixed gas is used for shielding, which assists with the stable welding arc with less spatter and minimal fumes.
SF-3Am has an excellent visual bead shape and smooth transition to the parent material.
SF-3AM is manufactured by Nippon Steel Welding & Engineering Co. Ltd and distributed in Australia and NZ by Welding Engineers NZ Ltd.
