| Base materials |
| Joining of stainless, stabilised Cr-Ni steels, e.g. 321 and 347. Due to the strengthening effect of Nb, 19.9.NbSi is recommended for weld metals subjected to temperatures above 400oC. |
| Resistance against corrosion |
| Good resistance to general and, owing to the low Nb content, intergranular corrosion. |
