1. UNCONTROLLED MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSD-308 FOR WELDING AUSTENITIC STAINLESS STEELS CONTAINING A NOMINAL 19Cr AND 10Ni DATA SHEET NO. 59 SPECIFICATION AWS A5.4 BS EN ISO 3581-A JIS Z 3221 CLASSIFICATION E308-15 E 19 9 B D308-15 PRODUCT DESCRIPTION A chemically basic flux with a low level of silicio us minerals together with small alloy additions to compensate for arc losses. The flux is concentrically extruded onto a fully al loyed core wire and bound by a blend of silicates that assures both coating streng th and resistance to subsequent moisture absorption. WELDING FEATURES OF THE ELECTRODE Suitable for use on DC+ only the arc is very forcef ul but the nature of the molten slag allows easy vertical up and overhead welding. Ideal for site welding as the extra shielding gas f rom 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 t he Chemical, Petro-Chemical and Cryogenic Processing and Storage Industries as well as the Food, Brewery and Pharmaceutical Industries using the following m aterials: ASTM 304 CF3 CF8 UNS S30400 S30453 Plus ASTM 301, 302, and 303 C Mn Si S P Cr Ni Mo Cu Fe FN MIN - 0.5 - - - 18 9.0 - - 3 MAX 0.08 2.5 1.0 0.03 0.04 21 11 0.75 0.75 10 WELD METAL ANALYSIS COMPOSITION % BY Wt.
