This specification covers columbium in the form of sheet, strip, plate, and foil. This material has been used typically for parts requiring exposure to ultra-high temperatures, but usage is not limited to such applications. Applications in oxidizing atmospheres necessitate a protective coating. Although produced in the cold rolled condition, this material is intended to be used in the annealed condition.
