ZIRCONIUM ALLOYS HAVING EXCELLENT RESISTANCE PROPERTY IN BOTH WATER AND STEAM REACTION

摘要

Zirconium alloying composition with a superior cooling water and steam corrosion resistance made in the high niobium content more than 5 weight% including chrome, and the oxygen and silicon of the trace amount. Zirconium alloying composition with a superior cooling water and steam corrosion resistance comprises niobium 1.5 ~ 2.0 weight%, Chrome 0.05 ~ 0.3 weight%, oxygen 800 ~ 1500 ppm, silicon. 60 ~ 100 ppm, copper 0.01 ~ 0.5 weight%, iron 0.05 ~ 0.3 weight% or copper 0.1 weight% and iron 0.05 weight%, and the remnant zirconium.
