Dual Shield Prime 81Ni1M H4
A seamless, copper free, cored wire designed to weld thick steel components. The diffusible hydrogen level is consistently below 4mL/100g of deposited weld metal and with the seam of the wire being laser welded this ensures no moisture pick up. The wire is not copper coated, which means there is no chance of copper flakes contaminating feed liners, torches and contact tips. Dual Shield Prime 81Ni1M H4 is designed to weld high strength steels (>500 MPa, >72 ksi yield strength) and provides excellent impact toughness down to -60° C (-76° F). Dual Shield Prime 81Ni1M H4 is designed to be used with Ar/CO2 (M21) shielding gas mixtures.
