RA333
UNS N06333
Description
RA333 is a superalloy with high chrome nickel base with excellent high temperature resistance, corrosion resistance and good workability.
- High temperature resistance: RA333 alloy has excellent strength at high temperature and creep resistance. It can withstand the repeated thermal shock of oil or water quenching and can maintain stable mechanical properties at high temperatures with maximum operating temperature of 1095 °C.
- Corrosion resistance: RA333 alloy can resist many strong acids, alkali, chloride and other corrosive media. Further, it is one of the few materials that can withstand corrosive conditions ranging from aqueous to white heat.
- Workability: RA333 alloy has good malleability and formability, which can be machined and formed into a variety of complex parts after quenching and annealing treatment.
