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.
This list of terms, with accompanying photomicrographs where appropriate, is intended as a guide for use in the preparation of material specifications.
This specification covers established manufacturing tolerances applicable to titanium and titanium alloy tubing. These tolerances apply to all conditions, unless otherwise noted. The term "excl" is used to apply only to the higher figure of the specified range.
