Descripción y aplicaciones
• Basic flux cored super duplex stainless steel wire
• 25% chromium - 9% nickel - 4% molybdenum - copper - nitrogen - low carbon deposit
• Exclusive slag system and fine tuning of the compositional balance insure good impact toughness levels
• PREN > 40, CPT tested at 45°C
• Excellent weld metal quality and X-ray soundness
• Maximum performances in the horizontal and downhand positions
• Classical economical Ar-CO2 mixtures 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
