▎Applications and Features

  • Weld metal is 19.5% Cr-10% Ni-Nb, which adds Nb in order to reduce carbide precipitation.
  • It is suitable for welding AISI 347, 321, 304L and 302 stainless steel

▎Welding Instruction

  • During Welding, the base metal of the weld deposit will dilute and produce ferrite or pure austenitic, which will increase the bead cracking resistance.
  • For other instructions, please refer to Appendix D.
  • For extra information, please refer to Appendix F.

▎Applications

It is suitable for welding AISI 347, 321, 304L and 302 stainless steel.
