FCW Sub 309L
Description & applications
DESCRIPTION
- Cored stainless steel wire for submerged arc welding
- 24% chromium - 13% nickel - low carbon deposit
- Attractive bead appearance without residual slag, outstanding slag release even in narrow gaps
- Excellent weld metal quality and X-ray soundness
- High productivity
- Enhanced wetting properties compared to matching solid wires
APPLICATIONS
- Welding stainless steels of similar composition or ferritic stainless steels.
- Joining stainless steels to mild and low-alloyed steels.
- Rebuilding and buffering before cladding or hardfacing.
- Maintenance on « hard-to-weld steels ».
Examples
Dissimilar welds between stainless steels type 304, 304L, 316, 316L, 318, 316Ti, 321, 410 or ferritic stainless steels type 1.4713, 1.4724, 1.4742, 3Cr12, to non or low alloyed CMn steels, for service temperatures up to 400°C.
