Select 8000-SR

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Designed for welding high strength, low alloy steels that require exceptional low temperature toughness in the as-welded or stress relieved conditions.
  • Maintains tensile strength and high toughness at low temperatures after long term or repeated post weld heat treatment cycles.
  • Ideal for pressure vessels, storage tanks, flanges, and valves, and piping and repair applications.
  • Maintains low hardness in the as-welded and PWHT conditions
