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 400°C.
Resistance against corrosion
Good resistance to general and, owing to Nb content, low intergranular corrosion. The Mo content gives good resistance also to pitting.
