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.
Note 1UNS K92801 should only be considered for use at service temperatures below 300C. The alloy is prone to sigma phase formation and associated brittle mechanical behavior after prolonged exposures at temperatures close to 475C.
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.
