TYPICAL APPLICATIONS
• Weld metal 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
• Dilution of base metal produces ferrite or pure austenitic to increase crack susceptibility.
SHIELDING GAS : CO2 or (80% Ar + 20% CO2 mix gas)
WELDING POSITION : Down hand
