Descripción
Características:
LFC-811A1 is a 0.5% Molybdenum alloyed flux cored wire which prevents deterioration in tensile strength after stress relief and extended service temperature. With good weldability ,stable arc and efficiency in all position welding.
Aplicaciones:
It is suitable for welding high-strength and matching creep-resisting steels.
Notas sobre el uso:
1. Use DC(+) polarity.
2 .Use 100% CO2 shielding gas.
3. Pre-heat at 100-200oC and PWHT at 600-650°C.
