Eigenschaften und Anwendungsgebiete

• Metal cored super duplex stainless steel wire for gas shielded metal arc welding

• 25% chromium - 9% nickel - 4% molybdenum - copper - nitrogen - low carbon deposit

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

• Excellent weld metal quality and X-ray soundness

• Nitrogen free classical shielding gases are used for welding

APPLICATIONS

Welding super duplex grades in downhand and flat position when increased impact toughness is required.

Heterogeneous welding between super duplex stainless steels and other stainless and mild or low alloyed steels
