Select 90C-M2

Low Alloy / Metal Cored / Gas Shielded

Resources

Features

  • Select 90C-M2 is a premium, composite metal cored electrode, exhibiting superb welder appeal and outstanding mechanical properties.
  • Intended for single and multiple pass welding of certain low alloy steels, in the flat and horizontal positions, where a minimum tensile strength of 90,000 psi is required in the deposited weld metal.
  • The recommended shielding gas is 90% Argon- 10% CO₂. Other Ar-CO₂ mixtures may be employed, with a minimum of 75-80% argon.
  • Select 90C-M2 is an ideal choice for joining low alloy, high strength steels such as HY-80, A514 and A710.
  • Earthmoving equipment, mining trucks and machinery, and heavy equipment trailers are some areas where this electrode may be utilized.
  • Ideal for those applications where the slag residue and fume emissions of flux cored electrodes are unwanted.
