Product application instructions
APPLICATIONS
FCW Sub 318L is suitable for joining stabilized stainless steels with an alloying element content of 16-21% Cr, 6-13% Ni and up to 3% Mo. This wire is also used for hardfacing applications.

| AISI | UNS | Material number | EN Symbol |
| 316Ti | S31635 | 1.4571 | X6 CrNiMoTi 17-12-2 |
| 316Cb | S31640 | 1.4580 | X6 CrNiMoNb 17-12-2 |
| 318 | S31640 | 1.4583 | X10CrNiMoNb 18-12 |
Welding positions
EN ISO 6947:PA, PB.
ASME IX:1F, 1G, 2F.
FCW Sub 318L 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
