Select 70C-6SR

Carbon Steel / Metal Cored / Gas Shielded

Resources

Features

  • Select 70C-6 SR is a premier carbon steel, composite metal cored designed to produce excellent mechanical properties in the as-welded and stress relieved conditions.
  • Maintains excellent mechanical properties after extended stress relief up to 8 hours
  • Possesses excellent notch toughness at -60°F before and after post weld heat treatment
  • Metal cored formula promotes increased travel speed with better sidewall fusion and few silicon islands
  • True spray transfer with virtually no spatter
  • Very low diffusible hydrogen levels of less than 4.0mL/100g
