1. MANUFACTURERS OF A DIVERSE RANGE OF ADVANCED WELDING CONSUMABLES SECTION 6 NSD-347 FOR WELDING STABILISED AUSTENITIC STAINLESSS STEELS CONTAINING A NOMINAL 19 Cr and 10Ni DATA SHEET NO. 75A SPECIFICATION AWS A5.4 BS EN 1600 JIS Z 3221 CLASSIFICATION E347-15 E 19 9 Nb B D347-15 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 Industrie s using the following materials: ASTM-ASME 321 347 CF8C (cast) UNS S32100 S34700 NSN-347 is designed to weld Nb and Ti Stabilised Austenitic Stainless Steels at service temperatures between 100 º C and 400 º C.
