AWS ER 316LSi
Base materials
Joining of stainless Cr-Ni-Mo and Cr-Ni steels, stabilised or non-stabilised, e.g. 316, 316L and 316Ti as well as 304, 304L, 321 and 347, for service temperatures up to 400oC. Also for stainless Cr steels with max 19 % Cr.
Resistance against corrosion
Good resistance to general and, owing to low C content, intergranular corrosion. The Mo content gives good resistance also to pitting.
