Solid wire with low carbon concentration designed for welding stainless steel with 23% Cr and 13% Ni content with service temperature in the range of -80°C and 300°C. Suitable for heterogeneous welding, generally between dissimilar steels, stainless and carbon-manganese steels. It is used for joints and cushion layers for stainless filler metal. Thanks to the higher silicon content its arc stability gets improved, it gives good-looking weld bead and very limited spattering. To be used under the shield of Ar 98% + O2 2%.
