Nihonweld NSW-308L description: A general purpose stainless steel Shielded Metal Arc Welding electrode for welding 18/8 austenitic stainless steels. NSW-308L-16 deposits a low carbon 18% Cr-8% Ni weld metal to provide good corrosion resistance properties to intergranular attack from a range of liquid chemical media at service temperatures up to 300C. Welds with a smooth even metal transfer and stable arc, and is practically spatter free. Finely-ripped bead and self-peeling slag. Easy welding in all positions. The striking and restriking of the electrode is remarkably easy. A self releasing slag and the risk of porosity in the weld is minimal provided the electrode is dry. The finished welds exhibit a slightly concave shape with good cosmetic appearance which requires little or no post weld dressing. The electrode is ideal for both fillet and butt welding applications. The smaller sizes including 3.25mm are suitable for positional welding while the bigger sizes are for flat only.
