Eigenschaften und Anwendungsgebiete

DESCRIPTION

- Metal cored stainless steel wire for gas shielded arc welding

- 24% chromium - 13% nickel - low carbon deposit

- Enhanced productivity, improved weldability, better wetting properties compared to solid wires

- Excellent weld metal quality and X-ray soundness

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 CrNiMo stainless steels and mild or low alloyed CMn steels, for service temperatures up to 350°C. Tube S 309LMo-G has superior resistance to dilution when compared to 309L

deposits because of its higher alloy and ferrite content. Compared to the AWS 312 weldments it benefits from an improved strength/ ductility balance.
