KMS-347Si
Shielding Gas: Ar+1~2%O2(CO2)
Weld metal is austenitic structure with 19%Cr-9%Ni-Nb
Ideal for welding AISI 308H, 321 and 347 stainless steel plates

Classification


Application and Features 

• Weld metal is austenitic structure with 19%Cr-9%Ni-Nb
• The addition of niobium reduces intergranular corrosion in severe operating conditions
• High silicon level for increased puddle fluidity and toe wetting
• Ideal for welding AISI 308H, 321 and 347 stainless steel plates

Welding Position


Welding Instruction

• Use Ar+1~2%O2 for spray transfer and Ar+1~2%CO2 for short-circuit transfer.
• For other instructions, please refer to Appendix B and F

Application
- Ideal for welding AISI 308H, 321 and 347 stainless steel plates
