To provide a heat treatment member and the like that, even when repeatedly loaded into a heat treating furnace, suppresses the occurrence of deformation, cracking, and the like, allowing use for a prolonged period of time, and enables uniform and sufficient carburizing treatment of a part to be heat-treated. The above-described problem is solved by a heat treatment member constituting a heat treatment structure repeatedly loaded into a heat treating furnace with a part to be heat-treated placed thereon, hooked thereto, or the like, comprising an ST member composed of a steel material or a Ni alloy material and a CC member composed of a carbon composite material being detachably combined. At this time, the ST member is preferably a member fabricated by a lost wax process, and the heat treatment member is preferably a hooking member for hooking the part to be heat-treated, a support member for supporting the hooking member, a mounting member for mounting the part to be heat-treated, or a stacking auxiliary member or a support column member for stacking each of these members.
A member 10 for heat treatment constituting a structure 60 for heat treatment, said structure being repeatedly brought into a heat treatment furnace, while having a component to be heat treated mounted or hung thereon. This member 10 for heat treatment has a configuration wherein an ST member 1, which is formed of a steel material or an Ni alloy material, and a CC member 2, which is formed of a carbon composite material, are combined with each other in a detachable manner, and is suppressed in the occurrence of deformation, cracking and the like even if repeatedly brought into a heat treatment furnace, thereby being usable for a long period of time and enabling a uniform and sufficient carburizing treatment of a component to be heat treated. It is preferable that the ST member 1 is produced by a lost wax process; and it is also preferable that the member 10 for heat treatment is a hanging member 10A on which a component to be heat treated is hung, a supporting member 10B which supports the hanging member 10A, a mounting member 10C on which a component to be heat treated is mounted, a stacking assistant member 10D for stacking these members, or a support column member 10E.

The present invention provides a tray member for heat treatment in which the occurrence of deformation and cracking is suppressed and which can be used for an extended period of time even when loaded with parts and repeatedly placed in a heat treatment oven in order to heat-treat the parts. The abovementioned problem is solved by a tray member (10) for heat treatment, the tray member being constituted of a tray (1) and a plurality of part receptacles (2) detachably mounted on the tray (1), and being repeatedly placed in a heat treatment oven along with parts to be heat-treated, wherein the tray (1) comprises a base (11) having a plurality of mounting sections (13) enabling the part receptacles (2) to be mounted at prescribed positions, and the base (11) and corner support rods (12) are formed of a carbon composite, steel, or a nickel alloy. The corner support rods (12) are provided at corners (15) of the base (11) to allow multiple trays (1) to be stacked, and one or more center support rods (17) are preferably provided at or near the center of the base (11).
