CB909 Super Rod, A superior SUPER Strength Electrode for welding High Alloy and Dissimilar Steels, AC or DC Reverse GENERAL CHARACTERISTICS: A premium electrode designed to produce the highest tensile weld, Features low heat input. Produces smooth porosity free welds without undercut or spatter in all positions. APPLICATIONS: Can be used for practically all maintained repairs. Used to weld low, medium and high alloy steels requiring the highest tensile strength and quality. Excellent for the repair of carbon steels, stainless steels, pressure vessels, aircraft steels, tools, dies, springs and vanadium-moly spring steels. Used to build-up prior to hardfacing. Use to join stainless steel of unknown analysis to carbon steels. Use fro rebuilding blades and shafts, used in construction, mining and chemical industries. Excellent for broken stud removal. TECHNICAL DATA: Tensile Strength as welded......up to 120,000 psi, work hardened.......up to 180,000 psi. Yield Strength......up to 90,000 psi. Elongation %......Aprox 28% Hardness (HB) approx 300 About 14 rods per pound
