1、Designation: B392 091Standard Specification forNiobium and Niobium Alloy Bar, Rod, and Wire1This standard is issued under the fixed designation B392; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numb
2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEEditorial corrections were made throughout in January 2010.1. Scope1.1 This specification covers four grades of wrought nio-bium and niobium alloy
3、 bar, rod, and wire as follows:1.1.1 R04200-Type 1Reactor grade unalloyed niobium,1.1.2 R04210-Type 2Commercial grade unalloyed nio-bium,1.1.3 R04251-Type 3Reactor grade niobium alloy con-taining 1 % zirconium, and1.1.4 R04261-Type 4Commercial grade niobium alloycontaining 1 % zirconium.1.2 The valu
