Flux Cored Wires LFC-312 E312T1-1

▶︎ Characteristics:

LFC-312 is designed for welding of high carbon steels and for the first layer cladding of carbon and low alloy steels. The best results are obtainable when the buttering technique is used.

 


 

▶︎ Applications:

It is suitable for welding buttering and cladding of austenitic steels types 303, 416, 430F

 


 

▶︎ Notes on Usage:

1. Use 100% CO₂ shielding gas.
2. Keep dry while in storage and delivery.
3. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
