摘要： 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.

摘要： A heat-treatment tray member comprises a tray, and a plurality of part receivers detachably mounted onto the tray. The tray includes a base part provided with a plurality of mounting parts capable of mounting the plurality of part receivers in predetermined positions, and the base part and corner support columns are constituted by a carbon composite material, or a steel material or a nickel alloy material. The corner support columns are provided to corners of the base part to layer a plurality of the trays, and one or two or more center support columns are preferably provided at or near a center of the base part.
