1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 5 RD-96B3 LOW HYDROGEN - IRON POWDER ELECTRODE FOR WELDING 2.25Cr-1Mo STEELS SUBJECTED TO SERVICE AT ELEVATED TEMPERATURES DATA SHEET NO. 51 SPECIFICATION AWS A5.5 BS EN ISO 3580B JIS Z 3223 CLASSIFICATION E9016-B3 E6216-2C1M DT2416 PRODUCT DESCRIPTION The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met. The basic flux containing the appropriate alloying elements with a controlled balanced addition of iron powder, is extruded onto a high purity ferritic core wire with a blend of silicated that ensures both coating strength and a coating resistant to subsequent moisture absorption . WELDING FEATURES OF THE ELECTRODE The chemical nature of the flux together with a significant proportion of iron powder ensures maximum deposition efficiency without detracting from its ability to be used in all positions except vertical down. Overall the arc is very stable, slag detachability is good and metal recovery is some 115% with respect to the core wire.
