Innershield® NR®-203 Nickel (1%)

Flux-cored self-shielded (FCAW-S) Wire

AWS: E71T8-Ni1-H16, E71T8-A2-Ni1-H16

Innershield® NR®-203 Nickel (1%) from Lincoln Electric is designed to produce a nickel bearing weld deposit with impact properties capable of exceeding 27 J (20 ft·lbf) at -29°C (-20°F).

DETAILS

Designed to produce a nickel bearing weld deposit with impact properties capable of exceeding 27 J (20 ft·lbf) at -29°C (-20°F). It handles poor fit-up in the vertical up position and welds gaps up to 9.5 mm (3/8 in).

Features

  • Designed to produce a nickel bearing weld deposit
  • Capable of producing weld deposits with impact toughness exceeding 27 J (20 ft·lbf) at -29°C (-20°F)
  • Color match on weathering steels
  • Handles poor fit-up
  • Root bead capability
