Applications and Features

( 1 ) Weld metal is austenitic structure with 20%Cr-9%Ni-6%Mn.

( 2 ) High silicon level for increased puddle fluidity and toe wetting.

( 3 ) 6% Manganese (Mn) increases resistance to hot cracking.

( 4 ) Suitable for welding work hardening manganese steel and armor plate.

( 5 ) Designed for joining dissimilar stainless steel.

Welding Position

Welding Instruction

( 1 ) Use Ar+1~2%O₂ for spray transfer and Ar+1~2%CO₂ for short-circuit transfer.

( 2 ) For other instructions, please refer to Appendix B and F.
