1、Designation: B511/B511M 16Standard Specification forNickel-Iron-Chromium-Silicon Alloy Bars and Shapes1This standard is issued under the fixed designation B511/B511M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last
2、 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. Scope1.1 This specification2covers wrought alloys UNS N08330and UNS N08332 in the form of hot-finished and cold-finishedbar and sha
3、pes intended for heat-resisting applications andgeneral corrosive service.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the othe
4、r. Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to become familiarwith all hazards including those ide
