METALLIC MATERIAL FOR HYDROTHERMAL-REACTION TREATMENT APPARATUS, AND HYDROTHERMAL-REACTION TREATMENT APPARATUS

摘要

PPROBLEM TO BE SOLVED: To provide a metallic material for a hydrothermal-reaction treatment apparatus, which controls an extent of corrosion caused by a hydrothermal oxidation reaction in a supercritical state or a subcritical state, to a corrosion loss of 1 mm or less per year, and to provide the hydrothermal-reaction treatment apparatus. PSOLUTION: The metallic material for the hydrothermal-reaction treatment apparatus, which composes the hydrothermal-reaction treatment apparatus used for the hydrothermal reaction in the supercritical state or the subcritical state, is made of a Ni-based alloy including Ni as a main component, 14-30 mass% Cr, and 2 mass% or less Mo or substantially 0 mass% Mo. The hydrothermal-reaction treatment apparatus 1 is composed of the above metallic material for the hydrothermal-reaction treatment apparatus. PCOPYRIGHT: (C)2005,JPO&NCIPI
