Corrosion-resistant electrodes
for pump welding

Electrode manufacturer Select-Arc Inc has introduced a duplex stainless steel electrode range which has good resistance to intergranular corrosion, pitting and stress cracking in piping systems, pumps, valves and heat exchangers.

SelectAlloy 2553-AP is a flux cored, all position electrode with a nominal composition of 25.5% chromium, 9.5% nickel, 3.5% molybdenum and 0.15% copper. The weld metal in SelectAlloy 2553-AP exhibits high strength with outstanding corrosion resistance, especially to pitting attack from chlorides in sea water. As well as pipeline applications, the wire is also utilized for welding in the chemical and fertilizer industries.

The electrode produces little or no slag and virtually no spatter and give a smooth, stable arc transfer.
