Abstract

This specification covers foils, sheets, strips, and plates made from UNS R04295 hafnium alloyed niobium ingots and billets. The materials should be in the annealed condition unless otherwise specified. The materials may also be in a forged, rolled, extruded, swaged, or drawn finish in a cleaned, machined, or ground condition. All the products should be formed with conventional extrusion, forging, and rolling equipment normally used in metal working plants.

Scope

1.1 This specification covers hafnium alloyed niobium foil, sheet, strip, and plate.

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

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

1.4 The following safety hazards caveat pertains only to the test methods portion, Section 14, of this specification: This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
