DETAILS

Metalshield® MC®-90 from Lincoln Electric is a low alloy metal-cored wire designed for high strength welding where tensile requirements of 620 MPa (90ksi) are required.

Features

  • H4 diffusible hydrogen levels
  • Low spatter and excellent arc stability
  • Deoxidizing agents minimize pre- and post-weld clean up
  • Enhanced silicon island management
  • Low temperature impact properties - charpy V-notch test results capable of exceeding 40 J (30 ft·lbf) at -51°C (-60°F)
  • Excellent bead shape and profile

Typical Applications

  • Robotics/hard automation
  • HSLA steels (i.e., ASTM A678 and A710)
  • Crane fabrication
  • Structural

Welding Positions

  • All

Shielding Gas

  • Mixed Shielding Gas
