Descrizione
Caratteristiche:
LFC-308 is a special for 100% CO₂ gas and all-position welding. With excellent slag removal, good resistance to intergranular corrosion and has higher tensile strength than LFC-308L.It also can be used as an intermediate layer for hardfacing.
Applicazioni:
It is suitable for weldingof 18Cr-8Ni austenitic steels such as AISI304, AISI301, AISI302, SUS304H.
Note sull'uso:
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.
