1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSB-316H FOR WELDING AUSTENITIC STAINLESSS STEELS CONTAINING A NOMINAL 19Cr-12Ni-2.5Mo DATA SHEET NO. 73 SPECIFICATION AWS A5.4 BS EN 1600 JIS Z 3221 CLASSIFICATION E316H-16 E19 12 2 R D316-16 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 smooth, 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 using the following materials: ASTM 316/316H CF10M UNS 310 S51 316 S53 S316 C16 NSB-316H is designed to weld 316, 316H Austenitic Stainless Steels operating at 500 º C to 800 º C under long-term creep conditions.
