Polaris A, Low-Hydrogen Electrode for Repairing Crack Sensitive and Problem Steels, 3/32" Dia., 5lb, Rockmount Research And Alloys, Mfr#: 1703-5

Polaris AFor high strength alloy and problem steels. Also for Cor-Ten wear resistant and nickel bearing steels.Features:– Excellent Strength 95,000psi– Moisture Proof, Low Hydrogen– X-Ray Quality Welds– Outstanding Ductility (33% Elongation)– Excellent Sub-Zero Properties – Charpy At -20oF 82ft/lbs– Highest Impact Resistance– Crack-Free Results– Easy To Use in All Positions– Welds “Tramp” SteelsPolaris 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
