DETAILS

BLUE MAX® MIG 2594 is a super duplex grade electrode that provides matching chemistry and mechanical property characteristics to super duplex wrought and castings. The electrode is over-alloyed 2-3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld resulting in high tensile and yield strength and superior resistance to stress corrosion, cracking (SCC) and pitting corrosion

Features

  • Q2 Lot® - Certified Material Test Report showing actual wire composition, Country of Origin and calculated ferrite number (FN) of each lot is available online in the Certificate Center
  • Proprietary surface lubricant for steady feeding and arc stability leading to exceptional performance at high wire feed speeds
  • A super-duplex grade electrode that provides matching chemistry and mechanical property characteristics to wrought super-duplex alloys such as 2507 and Zeron 100% as well as to super duplex casting alloys (ATSM A890)
  • The electrode is over-alloyed 2-3% in nickel to provide the optimum ferrite/austenite ratio in the finished weld resulting in high tensile and yield strength and superior resistance to stress corrosion, cracking (SCC) and pitting corrosion

Typical Applications

  • Process Pipework
  • Pumps and Valves
