描述
特点
LFC-811B2 is a gas-shielded and rutile flux cored wire intended for 1-1.25%Cr-0.5%Mo low alloy steel. Use 100% CO₂ shield gas.With good weldability ,stable arc, less spatter and good bead appearance in all position welding.
应用:
It is suitable for welding Cr-Mo steel pipe and Cr-Mo steel with requiring high creep resistance.
使用说明：
- Use DC(+) polarity.
- Use 100% CO₂ shielding gas.
- Pre-heat at 150-300ºC and PWHT at 620-720ºC.
