MEGAFIL® 281 M Metal Cored Arc Welding (MCAW) Low Alloyed

MEGAFIL® 281 M is a  seamless metal cored wire for which deposits 0.7%Ni/0.5%Cr/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. Suitable for robot applications and ideal for use in short and spray arc. Excellent impact toughness properties down to -60°C.

Applications:  Weathering steels, Steel Structure, General Fabrication, Offshore etc.
