1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSD-316L FOR WELDING LOW CARBON AUSTENITIC STAINLESSS STEELS CONTAINING A NOMINAL 19Cr-12Ni-2.5Mo DATA SHEET NO. 70 SPECIFICATION AWS A5.4 BS EN 1600 JIS Z 3221 CLASSIFICATION E316L-15 E 19 12 3 L B 12 D316L-15 PRODUCT DESCRIPTION A chemically basic flux with a low level of silicious 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 Suitable for use on DC+ only the arc is very forceful but the nature of the molten slag allows easy vertical up and overhead welding. Ideal for site welding as the extra shielding gas from the basic minerals ensures safety against porosity, even in windy conditions. APPLICATIONS AND MATERIALS TO BE WELDED Applications for the electrode are to be found in the Chemical, Petro-Chemical and Cryogenic Processin g and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries using the following materials: ASTM 316 316L 316LN CF3N CF8M UNS S31603 S31600 S31653 NSD-316L electrodes are use for their good resistance to corrosion and pitting against many acids on Austenitic Stainless Steels with 1.5 to 3.0 Mo plus Nb and Ti stabilised versions.
