Select 91-D3

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Formulated to match the mechanical properties and corrosion resistance of certain presssure vessel steels
  • Good welder appeal with excellent bead profile and low spatter levels
  • Manganese-molybdenum alloying make this a well suited filler metal for joining steels such as:ASTM A302 Gr. B, A49, A291, and A735.
