Select 810-B2

Low Alloy / Flux Cored / Gas Shielded

Resources

Features

  • Select 810-B2 is a low alloy steel electrode for flux cored arc welding with external gas shielding.
  • Designed for Cr-Mo steel plate and pipe, where 1¼% Cr and ½% Mo are required in the weld deposit.
  • Carbon dioxide is the recommended shielding gas; mixtures of 75-80% argon-balance carbon dioxide may be employed.
  • The smooth arc transfer, low spatter, and fast freezing slag make this an excellent choice for welding boiler and pressure vessel components in all positions.
  • Requires careful control of preheat and interpass temperatures, as well as proper post weld heat treatment.
  • Select 810-B2 is intended to weld steels subject to high temperature service, such as A387 Gr. 11 plate and A335 P11 pipe.
  • Typical applications include the fabrication of boilers, heat exchangers, and pressure vessels.
  • The AWS classification requires no minimum toughness values for this electrode; therefore, any specific toughness requirements should be discussed prior to use of the electrode.
