描述
特点
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.
应用：
It is suitable for welding high-strength and matching creep-resisting steels.
使用说明：
1. Use DC(+) polarity.
2 .Use 100% CO2 shielding gas.
3. Pre-heat at 100-200oC and PWHT at 600-650°C.
