Select 7000-SR

Carbon Steel / Flux Cored / Gas Shielded


Features

  • Designed for use with 75-80% Ar/balance CO₂ shielding gas
  • Intended to weld carbon steels of higher end applications, such ASTM A515-Gr 70, A516-Gr 70, A572, and A633
  • Weld deposits will deliver excellent CVN impact values, in the as welded and PWHT’d conditions at temperatures as low as -60°F
  • The slag system produces weld deposits with extremely low residual, or tramp, elements, which enhances low temperature and PWHT’d toughness
  • The enhanced mechanical properties make this a perfect choice to weld pressure vessels, valves, flanges, and piping systems in the power generation industry
