Patent ID: 8414828

Claim:
A corrosion resistant member for a supercritical ammonia reactor comprising a Ni-based corrosion resistant alloy, the Ni-based corrosion resistant alloy consisting essentially of: from 15% or more to 50% or less by mass of Cr; and at least one of Mo and W, wherein a [(content of Mo)+0.5 ×(content of W)] is from 1.5% or more to 8.5% or less by mass, and wherein the balance consists essentially of Ni and unavoidable impurities, wherein the corrosion resistant member comprising a Ni-based corrosion resistant alloy is formed as a covering layer on a surface that contacts with a supercritical ammonia fluid, and wherein the unavoidable impurities consist essentially of Fe in an amount of more than 0% to less than 3% by mass and C in an amount of more than 0% to less than 0.05% by mass.
