SL-71MAG

FIller Metal Breakdown

SL-71MAG

SL-71MAG is titania type Seamless Flux Cored Wire applicable for all position welding with Ar + 20~25%CO2 shielding gas. SL-71MAG offer optimal protection against moisture reabsorption. During use, moisture cannot penetrate into the filling since there is no closed seam running over the wire length. This extremely low level of diffusible hydrogen prevents the weld from hydrogen induced cracking or cold cracking.
