Description / Abstract:



1. Scope

1.1 This specification covers hafnium alloyed niobium ingots prepared by vacuum-arc melting or electron-beam furnace melting, or both, to produce consolidated metal for processing to various mill shapes.

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

1.3 The values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
