Descripción y aplicaciones
• Rutile flux cored stainless steel wire for gas shielded arc welding
• Specially designed for heat resisting applications
• Attractive bead appearance, very good penetration and high productivity
• Excellent X-ray soundness
• Specifically designed for out-of-position welding, maximum productivity for completion of vertical welds
• Welded with classical economical Ar-CO2 mixtures
APPLICATIONS
FCW V 309HT weld metal has a scaling temperature beyond 1000°C. The controlled carbon and ferrite levels improve microstructural stability and high temperature strength compared to the 309(L) types whereas the lower nickel content provides better resistance against sulphur attack than the 310 grade.
