ARCALOY 309Nb-15

Arcaloy 309Nb-15 was developed to inhibit carbide precipitation in this type of alloy. Best used out-of-position on DC current.

Features

Arcaloy 309Nb-15 was developed to inhibit carbide precipitation in this type of alloy when the maximum corrosion and oxidation resistance at elevated temperatures is required. This electrode has given excellent performance in the welding of airplane exhaust systems. Arcaloy 309Nb-15 is recommended for welding types 347 or 321 stainless clad steels, or type 347 stainless steel to carbon steel.
