Select 81-B2

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Intended for welding of certain Cr-Mo steel and pipe grades, where 1.25% Cr and 0.5% Mo are required in the weld deposit.
  • Ideal for welding steels subjected to high temperature service, such as ASTM A387-Gr 11 plate and A335 P11 pipe.
  • Typical applications include fabrication of boilers, heat exchangers, and pressure vessels.
  • Will harden in still air, thus it is critical that proper preheat and interpass temperatures are used as well as proper post weld heat treatment.
