KMS-312
Shielding Gas: Ar+1~2%O2(CO2)
Weld metal is austenitic structure with 29%Cr-9%Ni
Suitable for welding tool steels, hard to weld steels, cast and wrought alloys and dissimilar

Classification


Application and Features 

• Weld metal is austenitic structure with 29%Cr-9%Ni.
• High Cr content provides excellent corrosion resistance.
• High ferrite level in its austenitic structure provides better crack resistance.
• Suitable for welding tool steels, hard to weld steels, cast and wrought alloys and disimilar

Welding Position


Welding Instruction

• Weld metal becomes brittle at high service temperature or interpass temperature
• 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
- Suitable for welding tool steels, hard to weld steels, cast and wrought alloys and dissimilar alloy
