Select 81-A1

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Designed for flat or horizontal welding in single or multiple pass applications.
  • Addition of ~0.5 wt% molybdenum (Mo) provides increased high temperature strength compared to standard carbon steel electrodes.
  • Commonly used in fabrication and erection of boilers and pressure vessels.
  • Applications include the welding of C-Mo steel base metals (ASTM A161, A204, A302 Gr. A plate, and A335-P1 pipe).
