FCW SB 309H
Basic flux cored stainless steel wire for gas shielded metal arc welding
Descripción y aplicaciones
• 24% chromium - 13% nickel - high carbon deposit
• Exclusive slag system enables to get attractive bead appearance, excellent slag release, good penetration profile and high productivity
• Maximum performance in the horizontal and downhand positions
• Excellent X-ray soundness, ductility and unique impact toughness
• Welded with classical economical Ar-CO2 mixtures
FCW SB 309H is suitable for welding similar heat resisting alloys in wrought or cast form, for welding dissimilar metals or for joining steels which are difficult to weld, such as ferritic and martensitic 13% Cr steels.
