S 316 M-GF 221

Unitor S 316 M-GF is a rutile flux cored wire designed for welding 19% Cr, 12% Ni, 3% Mo types of stainless steel. It is also suitable for related stabilised steel grades if service temperature is below 400 °C. The wire operates with a very stable, spatter free arc producing a bright, smooth weld bead surface. The slag is self-releasing. As shielding gas use 80% Ar 20% CO2. When welding very thin sheet and pipes (less than 2 mm), TIG welding should be considered.

If there is an overlap joint (capillary joint) silver brazing should also be considered.
