A solid, smooth wire primarily intended for welding the low carbon, molybdenum alloyed, acid resistance 316L austenitic stainless steel of similar composition. Suitable for welding normal carbon 316 grade and Nb or Ti stabilized steel provided service temperatures are below 4000C. Widely used for chemical process plants. Deposits weld metal has improved resistance to general corrosion and pitting resistance in marine and industrial environments. The deposited weld metal is of radiographic quality.
WELDING CURRENT : DC(+)
SHIELDING GAS : Ar + 2% O2,16-21 1/min
CORROSION RESISTANCE : Good resistance to general and intergranular corrosion in the more severe environments e.g hot dilute acids. Good resistance to chlorise pitting corrosion.
