ZIRCONIUM BASED ALLOY - MITSUBISHI ATOMIC POWER IND

Title:

ZIRCONIUM BASED ALLOY

Document Type and Number:

Japanese Patent JPS63213629

Kind Code:

A

Abstract:

PURPOSE: To improve corrosion resistance and mechanical strength, by specifying the contents of Sn, Fe and Cr in a Zr based alloy as well as the total amount thereof and incorporating proper quantity of Nb into said alloy.

CONSTITUTION: The contents of the Zr based alloy contg. Sn, Fe, Cr and Nb are regulated, by weight, to 0.4W1.2% Sn, 0.2W0.4% Fe and 0.1W0.6% Cr, and the total amount of Sn, Fe and Cr is regulated to 0.9W1.5%; the content of Nb is further regulated to ≤0.5%. Since the compounded ratios of the elements to be added in said Zr alloy are regulated, the lowering of the amount of corrosive reaction by high-temp. water or high-temp. steam is improved at the time of using said alloy as the constitutional member in a nuclear reactor of an atomic power generation plant.
