Title:
An equipment configuration member consisting of nickel machine alloy excellent in corrosion resistance over fluoride fusion salt, and its nickel machine alloy
Document Type and Number:
Japanese Patent JP6041345
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a Ni-based alloy excellent in corrosion resistance to fluoride molten salts, as well as a device component that is made of the alloy and is used for a heat regenerator, a pump, piping or the like in a Th(thorium) molten-salt reactor.SOLUTION: A Ni-based alloy contains, by wt.%, Cr:6-8%, Mo:15-17%, Fe:0.05-2%, Mn:0.05-0.2%, Si:0.01-0.2%, V:0.001-0.08%, B:0.0001-0.01%, Mg:0.001-0.02%, N:0.001-0.04%, Al:0.005-0.1% and Ti:0.005-0.1% and further contains Cu:0.01-0.35% as required, and the balance is composed of Ni and inevitable impurities including C:0.01% or less. The Ni-based alloy is excellent in corrosion resistance to fluoride molten salts, and a device component made of the alloy is excellent in corrosion resistance to the fluoride molten salts.
