Exaton 19.12.3.LSi is used for welding of austenitic stainless alloys of 18% Cr - 8% Ni and 18% Cr - 10% Ni - 3% Mo-types, stabilized or non-stabilized, e.g. ASTM 316, 316L and 316Ti as well as 304, 304L, 321 and 347, for service temperatures up to 400°C (750°F). It is also used for welding of stainless Cr-steels with max 19% Cr. Exaton 19.12.3.LSi is particularly suited for MIG/MAG welding, but can also be used for automated TIG and PAW.
