Standard Specification for Zirconium and Zirconium Alloy Ingots
ABSTRACT
This specification covers the six grades of zirconium and zirconium alloy ingots: Grade R60700, Grade R60702, Grade R60703, Grade R60704, Grade R60705, and Grade R60706. These materials shall be manufactured by electron beam, vacuum, or inert atmosphere melting in furnaces. The material shall form to the required chemical composition of zirconium, hafnium, iron, chromium, tin, hydrogen, nitrogen, carbon, niobium, and oxygen. Check analysis shall be performed. The following test methods shall be done: ultrasonic test and chemical test.
SCOPE
1.1 This specification covers six grades of zirconium ingots.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following precautionary caveat pertains only to the test method portion, Section 10, of this specification: This standard does not purport to address all of the safety concerns, 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Zirconium and Zirconium Alloy Ingots
This standard is issued under the fixed designation B495; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers six grades of zirconium ingots.
1.2The 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.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.3 The following precautionary caveat pertains only to the test method portion, Section 10, of this specification: This standard
does not purport to address all of the safety concerns, 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.
