Austenite structure weld metal contains higher ferrite than other stainless steels. It contains higher Cr content in weld metal than others to get good oxidation and crack resistance.

Welding of 29% Cr - 9% Ni. It is suitable for dissimilar metal welding of stainless steel to low alloy steels or high Ni stainless steels. Shielding gas is 100% Ar (TIG) or Ar + 1~2% O2 (MIG)
