Mechanical Properties

  • Tensile Strength (Rm): ≥ 620 MPa (Typical: 680 MPa)
  • Elongation (A): ≥ 35% (Typical: 40%)
  • Charpy Impact Value (Akv) at -196°C: ≥ 30 J (Typical: 130 J)

Applications

  • Welding of 9% nickel steels for cryogenic applications down to -196°C (e.g., LNG tanks)
  • Dissimilar steel welding
  • Welding of problem metals
  • Storage and Handling:
  • Store in a dry place away from moisture and contaminants.
  • Maintain recommended storage temperature according to manufacturer's specifications (typically -10°C to +40°C).
  • Electrodes are hygroscopic (absorb moisture), follow recommended re-baking procedures if exposed to excessive moisture.

Safety Precautions

  • Welding fumes and gases can be hazardous. Ensure adequate ventilation during welding.
  • Wear appropriate personal protective equipment (PPE) including welding helmet, gloves, respirator, and clothing.
  • Avoid skin contact with electrode coating.
  • Keep flammable materials away from the welding arc.
  • Follow safe welding practices.
