IDENTIFICATION
GM 316LSi, ER 316LSi
CLASSIFICATION
AWS/SFA 5.9 ER316LSi
DESCRIPTION
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 400°C. 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.
