Product Description

  • Used in chemical processes that require alternate contact with strong acids and alkalis
  • Some of the major areas that ERZR-2 is used include heat exchangers, stripper columns, reactor vessels, pumps, valves, and corrosive media piping.
  • It has excellent resistance to corrosive attack in most organic and mineral acids, strong alkalis, and some molten salts.
  • This alloy is most commonly welded by the gas tungsten arc welding (GTAW) technique. Other welding methods include metal arc gas welding (MAGW), plasma arc welding, electron beam welding and resistance welding
  • TIG Wire marked with AWS classification
  • Ultra clean finishing
  • Certified Material Test Reports on all heats
