OK Aristorod 89
The non copper coated OK AristoRod 89 is a low-alloyed, chromium-nickel-molybdenum (0,4% Cr, 2,2% Ni, 0,55% Mo), solid wire for GMAW of ultra high tensile strength steels requiring tough weld metal for critical applications. Also suitable when high impact strength at lower temperatures is required. The AristoRod wires are suitable for operating at high currents with maintained disturbance free wire feeding giving a stable arc with a low amount of spatter, due to its unique Advanced Surface Characteristics ASC) technology. OK AristoRod 89 is delivered on spools or in the unique ESAB Marathon Pac, which is excellent in mechanised welding applications.
