Scope

1.1 This specification covers two chromium-iron alloys, the former, (UNS K91800), nominally 18% chromium, balance iron, the latter, (UNS K92801), nominally 28% chromium, in strip, bar, wire, and rod forms intended primarily for sealing to glass in electronic applications.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The following hazard caveat pertains only to the test method portion, Sections 16 and 17, 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.
