Select 70C-8

Carbon Steel / Metal Cored / Gas Shielded

Resources

Features

  • This product is intended for single and limited multiple pass welding of carbon steels, in horizontal fillet and flat position applications.
  • Select 70C-8 is ideal for those difficult-to-weld items such as heavily rusted and scaled surfaces or when the steel is coated with oil or paint, as it has special deoxidation that makes it very effective when welding over these surfaces or other contaminants.
  • There are several advantages over welding with solid electrodes; increased travel speeds, better fusion into base material and sidewalls, and the virtual elimination of subsurface porosity.
  • Strength levels and CVN toughness make it well suited for welding ordinary and fine grained steels such as ASTM A36, A285, A516, Grade 70 and A515 Grade 70.
  • SELECT 70C-8 is ideal for those difficult-to-weld items such as heavily rusted and scaled surfaces or when the steel is coated with oil or paint.
