Rockmount Polaris® A

For high strength alloy and problem steels such as cast steel, Cor-Ten, nickel bearing and high grade structural steels.

For high strength alloy and problem steels. Also for Cor-Ten wear resistant and nickel bearing steels. Polaris A avoids the moisture problems encountered with conventional low hydrogen electrodes. The exceptional elongation of Polaris A makes it ideal for applications involving impact or vibration. Polaris A produces sound, heat-treatable welds even on sulfur or caustic contaminated steels. Welds have extraordinary strength and ductility even at sub-zero temperatures. Deposits are easy to apply in all positions and are free machining.

Applications include all mining and construction equipment, boilers, tanks, piping, truck and bus frames, and all crack sensitive steels. Polaris A provides a good pad for hard surfacing due to its extraordinary ductility
