Product application instructions
APPLICATIONS
FCW Sub 347H is suitable for welding the higher carbon stabilised stainless steels containing 16 to 21% Cr and 8 to 13% Ni. The deposit has a controlled delta ferrite content and can be used above 550°C.
Examples
| AISI | UNS | Material number | EN Symbol |
| 321H | S32109 | 1.4941 | X8 CrNiTi 18-10 |
| 347H | S34709 | 1.4961 | X8 CrNiNb 16-13 |
Welding positions
EN ISO 6947:PA, PB.
ASME IX:1F, 1G, 2F.
FCW Sub 347H is primarily used in the flat and horizontal-vertical positions. However, welds in other positions are also possible using the short-circuiting or pulsed arc modes of transfer.
