1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSD-308L FOR WELDING LOW CARBON AUSTENITIC STAINLES STEELS CONTAINING A NOMINAL 19Cr and 10Ni DATA SHEET NO. 61 SPECIFICATION AWS A5.4 BS EN 1600 JIS Z 3221 CLASSIFICATION E308L-15 E19 9 L B D308L-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 Processing and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries using the following materials: ASTM 304L 304 304LN CF3 CF8 UNS S30403 S30400 S30453 Plus ASTM 301, 302 and 303 For all of the above, NSD-308L ensures matching resistance to corrosion.
