Flux Cored Wires LFC-911B3

Characteristics:

LFC-911B3 is a gas-shielded flux cored wire intended for 2.25%Cr-1%Mo low alloy steel. Use 100% CO2 shield gas.With good weldability ,stable arc, less spatter and good bead appearance in all position welding.

Applications:

It is suitable for welding Cr-Mo steel pipe and Cr-Mo steel with requiring high creep resistance.

Notes on Usage:

  1. Use DC(+) polarity.
  2. Use 100% CO2 shielding gas.
  3. Pre-heat at 150-300°C and PWHT at 620-720°C.
