MEGAFIL® 781 R Flux Cored Arc Welding (FCAW) Low Alloyed

MEGAFIL® 781 R is is a seamless rutile flux-cored wire which deposits 1%Ni/0,5%Cu weld metal designed for weather-resisting steels similar to Cor-Ten. Diffusible hydrogen levels will be less than 4ml/100g of deposited weld metal giving it more resistance to cracking. Excellent impact toughness properties down to -50°C. Applications: Weathering steels , Steel Structure, General Fabrication, Offshore etc.
