1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSB-309MoL FOR WELDING LOW CARBON AUSTENITIC STAINLESS STEELS CONTAINING A NOMINAL 23Cr-12Ni- 3Mo USED FOR DISSIMILAR WELDS BETWEEN STAINLESS AND C-Mn STEELS DATA SHEET NO. 66 SPECIFICATION AWS A5.4 BS EN 1600 JIS Z 3221 CLASSIFICATION E309LMo-16 E 23 12 2 L R D309MoL-16 PRODUCT DESCRIPTION A metallurgically advanced rutile based flux formulated with balanced additions of chemically basic, amphoteric and acid minerals, together with small alloy additions to compensate for arc losses. The flux is concentrically extruded onto a fully alloyed core wire and bound by a blend of silicates that assures both coating strength and resistance to subsequent moisture absorption. WELDING FEATURES OF THE ELECTRODE This unique flux formulation ensures excellent arc stability, ease of initial arc strike and re-strike minimal spatter on AC and virtually none on DC+. The resultant weld seams are smo oth, evenly rippled and free from undercut while slag detachability is excellent. Metal recovery is some 103% with respect to core wire weight. APPLICATIONS AND MATERIALS TO BE WELDED Applications for the electrode are to be found in the Chemical, Petro-Chemical and Cryogenic Processing and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries. Transition welds between stainless steel and ferritic steel welding clad plate or as a buffer layer on ferritic steel before completing with a more conventional low carbon austenitic stainless steel containing Mo, such as 316 and 316L.
