Product application instructions
APPLICATIONS
FCW Sub 310 is resistant to oxidation and scaling up to 1100°C. It is suitable for welding cast or wrought stainless steels of similar composition and heat resistant ferritic stainless steels.

| 310 | S31000 | 1.4841 | X15 CrNiSi 25-21 |
| 310S | S31008 | 1.4845 | X12 CrNi 25-21 |
Positions de soudage
EN ISO 6947:PA, PB.
ASME IX:1F, 1G, 2F.
FCW Sub 310 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.
