Description / Abstract:

This specification covers hafnium alloyed niobium ingots prepared by vacuum- or plasma- arc melting or electronbeam furnace melting, or a combination of these methods, to produce consolidated metal for processing to various mill shapes.

The material covered by this specification is Grade R04295, niobium-base alloy containing approximately 10 % hafnium and 1 % titanium.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
