Blue Max® MIG 2594

MIG (GMAW) Wire

AWS: ER2594

Designed to weld duplex and super duplex stainless steel

DETAILS

Blue Max® MIG wire is designed to perform exceptionally at high wire feed speeds

Features

  • 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)
  • Provides optimum ferrite/ austenite ratio in the finished weld, resulting in high tensile and yield strength, along with superior resistance to stress corrosion, cracking (SCC) and pitting corrosion
  • Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online

Typical Applications

  • Power Generation
  • Process Industries
  • Petrochemical

Welding Positions

  • All

Shielding Gas

  • 98% Ar/ 2% O2
