GM 316

SPECIFICATION : AWS/SFA 5.9 ER316 BS 2901-90 316S92 DIN 8556-86

CHARACTERISTICS :

A solid, smooth wire primarily intended for welding the low carbon, molybdenum alloyed, acid resistance 316 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
