TIG rod with low carbon concentration designed for welding stainless steel with 18% Cr and 8% Ni content with service temperature in the range of -100°C and 400°C. Thanks to the higher silicon content its arc stability gets improved, it gives good-looking weld bead and very limited spattering. It finds application in general and architectural fabrication, pharmaceutical equipment, food industry and nuclear engineering. High corrosion resistance in an oxidizing environment. To be used under the shield of 100% Ar .
