Applications and Features

( 1 ) Weld metal is austenitic structure with 25%Cr-20%Ni.

( 2 ) Suitable for welding AISI 310S steel and dissimilar metals (carbon steel, Cr-Mo steel and stainless steel).

( 3 ) Ideal for welding in chemical processing and nuclear plants, as well as for furnace and heat treatment equipment, due to the high scaling temperature and excellent oxidation resistance.

Welding Position

Welding Instruction

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

( 2 ) For welding dissimilar alloy, please refer to Appendix I.

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