Postalloy®303LH Flux-coated Electrode

EXCEPTIONAL LOW-HYDROGEN HIGH-STRENGTH ELECTRODE

Postalloy® 303LH is a low Hydrogen electrode for high strength steels, alloy and problem steels such as cast steel, Cor-Ten, nickel bearing and high-grade structural steels. 303LH produces sound X-Ray quality deposits with excellent subzero impact ratings. Welds have unusual strength and ductility even in some of the harshest environments. Welding is easy in all positions and deposits are free machining.
