KMS-309
Shielding Gas: Ar+1~2%O2(CO2)
Weld metal is austenitic structure with 23%Cr-12%Ni
Used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays

Classification


Application and Features 

• Weld metal is austenitic structure with 23%Cr-12%Ni
• Moderate ferrite content increases good crack and corrosion resistance
• Used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays
• Occasionally used for welding “18-8” base metals when severe corrosion conditions exist or dissimilar metals

Welding Position


Welding Instruction

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

Application
- Used for welding dissimilar materials such as mild steel to stainless steel, as well as for a barrier layer in stainless overlays
