Abstract
A zirconium alloy which imparts good creep strength, while also providing favorable neutron cross section, improved corrosion resistance, low hydrogen uptake and good fabricability is described which contains vanadium in a range of from an amount effective to indicate its greater-than-trace presence up to 1.0 wt %, wherein either limit is typical; niobium in a range of from an amount effective to indicate its greater-than-trace presence up to 1.0 wt %, wherein either limit is typical; antimony in a range of from an amount effective to indicate its greater-than-trace presence up to 0.2 wt %, wherein either limit is typical; tellurium in a range of from an amount effective to indicate its greater-than-trace presence up to 0.2 wt %, wherein either limit is typical; tin in a range of from an amount effective to indicate its greater-than-trace presence up to 0.5 wt %, wherein either limit is typical; iron in a range of 0.2 to 0.5 wt %, typically 0.35 wt %; chromium in a range of from 0.1 to 0.4 wt %, typically 0.25 wt %; silicon in a range of 50 to 200 ppm, wherein either limit is typical; and oxygen in a range of from an amount effective to indicate its greater-than-trace presence up to 2200 ppm, wherein either limit is typical and the balance zirconium.
