FOR WELDING STABILISED AUSTENITIC STAINLESSS STEELS CONTAINING A NOMINAL 19 Cr and 10Ni
NSD-347
CLASSIFICATION
AWS A5.4 E347-15 | EN ISO 3581-A E 19 9 Nb B | JIS Z 3221 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 Industries using the following materials: ASTM-ASME 321 347 CF8C (cast) UNS S32100 S34700 NSD-347 is designed to weld Nb and Ti Stabilised Austenitic Stainless Steels at service temperatures between 100ºC and 400ºC
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 150oC for 1 hour
