<P>PROBLEM TO BE SOLVED: To provide a nickel-containing metal apparatus material used at 380 to 520°C in an atmosphere containing chlorinated hydrocarbon and water, and having an excellent effect of suppressing the generation of caulking and corrosion, and to provide a reaction vessel using the metal apparatus material. Ž<P>SOLUTION: There are a nickel-containing metal apparatus material used at 380 to 520°C in an atmosphere containing chlorinated hydrocarbon and water, which is expressed by inequality (1) and a reaction vessel using the metal apparatus material: 5.0≤X≤ä62.2+0.27×(520-T)} (1); wherein, T is a temperature (°C) at which the material is used, and X (wt.%) repesents nickel content.
