Standard Specification for Zirconium and Zirconium Alloy Forgings — 3 стр.
Реферат

This specification covers three grades of zirconium and zirconium alloy forgings. The forgings shall be formed with conventional forging equipment normally found in primary ferrous and nonferrous metal plants. The forgings are furnished in three grades as Grade R60702, Grade R60702, and Grade R60705. Forgings shall be furnished in the annealed conditions. The material shall conform to the requirements as to chemical composition and tensile properties prescribed. Two tension tests shall be made from each lot. Two chemistry tests for hydrogen and nitrogen content shall be made from each lot of finished product. If the results of any tests of any lot do not conform to the requirements specified, retests shall be made on additional forgings of double the original number of the same lot, each of which shall conform to the requirements specified.

Область применения

1.1 This specification covers three grades of zirconium and zirconium alloy forgings.

1.2 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.

1.3 The following safety hazards caveat pertains only to the test method portion, Section 12, 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.
