Base materials
Joining of stainless Cr-Ni steels, stabilised or non-stabilised, e.g. 304, 304L, 321 and 247, for service temperatures up to 350oC. Also for stainless Cr steels with max 19 % Cr. Cryogenic applications down to -269oC, depending on welding process.
Resistance against corrosion
Good resistance to general and, owing to the low C content, intergranular corrosion.
