Unibraze 80S-B2is used to weld 1-1/4 chrome - 1/2 moly steels for elevated temperatures and corrosive service. Careful control of preheat, interpass temperatures, and post-weld heat treatment is necessary to prevent cracking. Unibraze 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 shielding gas is CO2 or an argon/CO2 mixture
