2、he case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers two iron-nickel alloys and oneiron-nickel-cobalt alloy, for

3、 low thermal expansion applica-tions. The two iron-nickel alloys, both containing nominally36 % nickel and 64 % iron, with the conventional alloydesignated by UNS No. K93603, and the free-machining alloydesignated as UNS No. K93050. The iron-nickel-cobalt alloy,containing nominally 32 % nickel, 5 %

4、cobalt and 63 % iron, isdesignated by UNS No. K93500. This specification defines thefollowing product forms for UNS No. K93603 and UNS No.K93500: wire, rod, bar, strip, sheet plate, and tubing. Thefree-machining alloy, UNS No. K93050, is defined for barproducts only. Unless otherwise indicated, all

5、articles apply toall three alloys.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This pertains only to the test method section,

6、Section 13.This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2. Reference
