Nickel, Corrosion and Heat-Resistant, Bars, Forgings, and Extrusions, Thoria Dispersion Strengthened, 2.2Th02, Stress-Relieved
This specification covers thoria-dispersion-strengthened nickel powder metallurgy product in the form of bars, forgings, extrusions, and stock for forging or extruding. These products have been used typically for parts required to operate in the range 1800 to 2400 °F (982 to 1316 °C), but usage is not limited to such applications. A protective coating is required for operation at such temperatures. Fusion welding of structural members is not recommended but the product can be brazed and resistance welded satisfactorily. Products covered by this specification are radioactive. Applicable rules and regulations pertaining to handling of radioactive material should be observed.
