FIELD: nuclear power engineering. SUBSTANCE: tube used for fuel assembly can or guide is characterized in that alloy has in its composition, mass percent: tin - 1.0-1.7; iron - 0.55-0.80; Cr or V - 0.20-0.60. In addition, alloy contains at least one of elements ( chromium or vanadium), and 0.10-0.18 mass percent of oxygen. Carbon and silicon content, %: 100 to 180 and 50 to 12, respectively; zirconium and inevitable impurities - the rest. EFFECT: reduced grain size in alloy structure. 13 cl |
