KFW-307 Flux/Metal Cored Wire

Description

KFW-307
Shielding Gas: 100%CO / Ar+20%CO
Weld metal is 20%Cr-9%Ni-6%Mn. It has good crack resistance

Classification


Application and Features 

• Weld metal is 20%Cr-9%Ni-6%Mn
• It has good crack resistance
• This wire’s relatively high manganese content helps reduce the chance of weld metal cracking in dissimilar metal welding

Welding Position


Welding Instruction

- For other instructions, please refer to Appendix D
- For extra information, please refer to Appendix F
- Use Ar blend with 1~2%O2 for high current, spray transfer welding
- Use Ar blend with 1~2%CO2 for low current, short-circuit transfer welding

Application
- This wire’s relatively high manganese content helps reduce the chance of weld metal cracking in dissimilar metal welding
