Exaton 19.12.3.LSiMo
Exaton 19.12.3.LSiMo 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.LSiMo is particularly suited for GMAW, but can also be used for automated GTAW and plasma welding. The critical pitting temperature, CPT, according to ASTM G150 (1°C of accuracy) can be as high as 39°C compared to standard 316LSi, which achieved maximum 29°C during the benchmark. The results were achieved with GMAW, but are expected to be on the same level or better for GTAW.
