RA333®
RA333® is a high chromium nickel base superalloy with outstanding resistance to high temperature oxidation and carburization. RA333® has an exceptional ability to withstand the repeated thermal shock of oil or water quenching. RA333® is one of the few materials that can withstand corrosive conditions ranging from aqueous to white heat. Upon shutdown, RA333® resists dew point corrosion by sulfuric acid and polythionic acid stress corrosion cracking.
Weld RA333 with matching composition N06333 bare wire or RA333-70-16 AC/DC coated electrodes. Do not preheat, keep interpass temperature below 212°F and use reinforced stringer beads. Machinability rating of RA333® is 12-15% of B1112; turn 20-25 sfm with high speed steel tools.
