SF-80A

SF-80A is a seamless, rutile flux cored wire designed for welding extra high tensile steels with min.690 mpa. The flux cored wire uses a Argon/CO2 mixed shielding gas which gives good weldability and a stable arc, minimum spatter, good visual bead and even transition to parent material. Due to the seamless design the wire has an extremely low hydrogen content (<4 ml/100g) which is very important when welding extra high tensile steels. The wire has a clean copper coated surface which together with exact diameter and roundness, ensures stable and even wire feeding. Wire stick out should be between 15-20mm dependent upon the welding parameters. Mechanical properties are designed for >47 joule at -40°C.
