MEGAFIL® 821 R is a seamless micro-alloy rutile flux-cored wire with rapidly solidifying slag for Ar-CO2 mix. The wire has excellent weld puddle manipulation, superior out-of-position weldability. Weld metal that conforms to NACE MR0175 in combination with low diffusible hydrogen, excellent fracture toughness down to -60 °C and CTOD test at -20°C makes this wire particularly suitable for critical applications in the pipeline and offshore industries. Idoneos when PWHT is required. MEGAFIL® 821 R provides low spatter loss and an easy slag removal. Applications: specialized shipbuilding, offshore steel structures, pipelines, steel and vessel construction, pipe work.
