Description
ER80S-B2 is used to weld 1¼% Cr – 1/2% Mo steels for elevated temperatures and corrosive service. Careful control of preheat, interpass temperatures, and post-weld heat treatment is necessary to prevent cracking. 80S-B2 is classified after post-weld heat treatment. Special care must be taken when using it in the as-welded condition due to higher strength levels. Recommended GMAW shielding gas is CO2 or an Argon/CO2 mixture.
