Classification:
EN ISO 14343 G 19 9 LSi
AWS A5.9 ER308LSi
Description:
Cromamig 308LSi is primarily intended for welding the low carbon 18% Cr / 10% Ni type 304 L
austenitic stainless steels. Suitable also for welding normal carbon grade 304 and Nb or Ti stabilised
steels (347, 321) provided service temperatures are below 400°C. The higher silicon content gives
better arc stability and weld metal flow which improves bead appearance, particularly when dip
transfer welding.
